13.1 Introduction

In 1964, the French social anthropologist and exponent of structuralism, Claude Lévi-Strauss, published volume one of his celebrated series Mythologiques: Le Cru et le Cuit, translated into English in 1969 as The Raw and the Cooked. In the volume’s introductory chapter, Lévi-Strauss offered an explanation of the group nature of the Amerindian myths analysed in the volume. With his arresting image of Indian America before the ages of European conquest as ‘a Middle Ages which was missing its Rome’, Lévi-Strauss invoked a – seemingly eternal – idea of ‘Rome’ as a source of order and normativity. For Lévi-Strauss, the structure of Amerindian mythologies differed from those of medieval Europe because there was no ‘Rome’ – neither empire nor Church – to act as a centralizing, structuring, unifying force. Nonetheless, as Lévi-Strauss’ Mythologiques set out to prove, there was structure to the seemingly ‘confused mass’ of Amerindian myth.Footnote ² I begin with Lévi-Strauss and his vision of ‘a Middle Ages which was missing its Rome’ in order to problematize the idea of centralized authority itself. More specifically, this chapter challenges the seemingly natural idea, typified here by Lévi-Strauss, that the presence of a Rome – or a Brussels, or a United Nations, or even a UNIDROIT – implies the development of a centralized, hierarchical model through which various, heteronomous, normative orders politely interact.

‘Rome’ here performs as shorthand for the deceptively complex idea that law and governance should be understood primarily in the context of imperium: the power to command. As Karen Alter states: ‘Most people presume that law is only meaningful when backed by a central enforcer.’Footnote ³ Hence for much of the twentieth century, in the absence of a ‘world state’, international relations could be conceptualized as operating outside the domain of law. Since 1989 the number of international courts has more than quadrupled in number from six to over twenty-four – resulting in the collective issuing of over 37,000 binding legal rulings in individual contentious cases.Footnote ⁴ Yet even this intensified judicialization of the international arena still tends to be framed by a persistent ‘image of law beyond the nation state as a weak ordering and regulatory system, rather than a constitutive element in the ongoing tumble of transnational life’.Footnote ⁵ The field of private international law – ‘the legal discipline that determines in which cases a court must apply a foreign law’ – also rests on a paradigm of Westphalian state governance.Footnote ⁶ Private international law ‘does not lay out substantive rules for such situations, but merely resolves conflicts between the legal orders themselves’, relying on relevant domestic choice-of-law principles and rules in order to resolve legal disputes with a foreign element.Footnote ⁷ As Neil Walker notes, choice-of-law rules ‘and the interpretative aids of transnational law do not “stand above” the domestic systems in which they are applied. Rather, they are formulated or interpreted each in the context of their own system – in deference to and under the self-validating terms prescribed by each domestic legal order’s sovereign authority.’Footnote ⁸ Notwithstanding the ‘equality’ between different domestic legal orders, the system of private international law prioritizes national sovereignty and is grounded within a hierarchical – in a Kelsenian sense – approach to international governance.

In contrast, the ‘postnational’ approach, as defined by Nico Krisch in his 2010 Beyond Constitutionalism: The Pluralist Structure of Postnational Law and further developed by the ‘Entangled Legalities’ project underlying this volume, argues that ‘national’ and ‘international’ law are interwoven to such an extent within the supranational legal order that norms and principles from both spheres interact heterarchically: ‘operating side-by-side without the presumptive authority of one over the other’.Footnote ⁹ Like Lévi-Strauss’ pre-conquest Amerindian myths, there is no centre or hierarchy (no ‘Rome’) to structure postnational law. Nonetheless, again like Lévi-Strauss’ account of Amerindian myth-making, there is a structure at work: ‘the nation-state itself shares ultimate authority with multiple regional and international legal orders with which it interacts without a common normative framework – hence a post-national law within a pluralist structure’.Footnote ¹⁰ Instead of mapping the contours of an emerging global constitutional framework in which overarching principles govern relations between different normative orders, this volume’s project seeks to reimagine the global legal order ‘through the paradigm of entangled legalities’:

We shall return to the idea of interface norms structuring ‘fluid and shifting relations between different bodies of norms’ in greater detail in Section 13.2. For the moment, we should simply note that the ‘postnational space seems to demand new, different, answers to the question of how to structure governance’.Footnote ¹²

Rafael Domingo has recently argued, in the context of ‘global constitutionalism’, that if the future of the supranational legal order is postsovereigntist, postnationalist and postpositivist, ‘Roman law was, so to speak, pre all of them: presovereigntist, prenationalist, and prepositivist’.Footnote ¹³ Most legal historians would agree, however, that there was something akin to ‘international law’ in Greco-Roman antiquity (and in earlier antiquity too): a rule of law that governed relations between states, alongside the use of brute force.Footnote ¹⁴ Historians of Greco-Roman ‘international law’ tend to focus predominately on the laws of war and diplomacy, including interstate peace treaties. Beyond the political and economic ordering of interstate relations, guaranteed by mutual oath-taking and divine invocation, Greco-Roman peace treaties also included clauses providing for the resolution of on-the-ground disputes that might otherwise threaten the newly agreed order. For example, the treaty concluded in 562 CE between the (Eastern) Roman Emperor Justinian I and the Sasanian King of Kings Xusro I set out – in both Greek and Persian languages – the terms of a fifty-year peace agreed between Rome and Sasanian Iran.Footnote ¹⁵ This 562 CE treaty contains two articles that could be compared loosely with modern ‘private international law’ provisions. Article 7 specifies that individuals who ‘have suffered some hurt at the hands of subjects of the other state’ should settle the dispute according to law: ‘either those who have suffered harm themselves, or their representatives, shall meet on the frontier before the officials of both states, and in this manner the aggressor shall make amends for the damage’.Footnote ¹⁶ Article 11, on the other hand, specifies the procedure to be followed in the case of intercity disputes that fall outside the ‘rules of war’:

There follow various provisions outlining what should happen if the judges from the frontier zone are unable to resolve a dispute, culminating in a referral to the relevant ruler and a one-year delay before the peace treaty is held to have been broken. The fact that the provisions of the 562 CE treaty itself were negotiated and concluded on the frontier between the Roman and Sasanian Empires, at the border city of Dara, is a further reminder of what the plural constitutionalist theorist Neil Walker terms the ‘centrality of the margins’.Footnote ¹⁸ Articles 7 and 11 of the 562 CE treatise, moreover, provide concrete examples of how action at the margins can be seen to structure an overall order. We shall return to this idea of the ‘centrality of the margins’ in Sections 13.2 and 13.3.

Whether there is anything in Classical or Postclassical Roman legal sources that could be mapped accurately onto the modern concept of ‘private international law’ is doubtful at best.Footnote ¹⁹ In fact, as we shall see in Section 13.3, the coordination of legal sources within the Roman Empire has more in common with the heterarchical approach of ‘postnational law’ than with the state sovereignty model of private international law. As Ulrike Babusiaux argues in a 2020 article comparing the legal ordering of imperial Rome with the legal ordering of the European Union, the question of ‘how to coordinate different legal sources without abstract hierarchy’ is an ancient one.Footnote ²⁰ During the late Roman Republic, practical and concrete jurisdictional questions arose in the context of Roman imperial expansion and the creation of the provincial system.Footnote ²¹ Contact between Roman citizens and ‘foreigners’ (peregrini, free citizens of any political community besides the Roman) was unavoidable, especially in relation to commerce and business dealings more generally.Footnote ²² Roman magistrates, legal experts (iurisperiti), the emperors and their officials were thus well aware of a world of private legal transactions involving ‘non-citizens’ of various different types and recognized the need to regulate those transactions from within the Roman legal system. At Rome, from at least the time of the first Emperor Augustus, the praetor peregrinus handled litigation between ‘foreigners’ and also cases between ‘foreigners’ and Roman citizens.Footnote ²³ The activity of the praetor peregrinus (and the praetor urbanus) at Rome may, to some extent, explain the origins of the Roman ius gentium: ‘those legal habits which were accepted by the Roman law as applying to, and being used by, all the people they met, whether Roman citizens or not’.Footnote ²⁴ The elaboration of this concept enabled Roman jurists to define certain private law interactions between peregrini, ‘Latins’ (who had some of the rights and privileges of Roman citizenship via Roman grants of the ius Latii) and Roman citizens, as falling under Roman jurisdiction. For example, peregrini could acquire ownership through ‘natural’ modes of acquisition (traditio, occupatio, accessio) and certain contracts of buying, selling and letting were also understood to be part of the ius gentium; slavery was iure gentium, all peoples had it although there were aspects of the (Roman) law of slavery that were peculiar to the Roman ius civile alone; and in certain Roman law actions a legal fiction even enabled foreigners to sue or be sued ‘as if’ they were Roman citizens.Footnote ²⁵ The important point to note here is that while Roman jurists and magistrates worked within a conceptual framework that acknowledged different ‘layers of law’ (Rechtsschichten), including the ius gentium, their start and end point was the resolution of cases – hypothetical and real – in accordance with the citizen-law of Rome itself.Footnote ²⁶ The opening of Gaius’ Institutes, a mid-second-century CE introduction to Roman law, famously refers to ‘all peoples who are governed by laws and customs’ as having their own bodies of citizen-law – yet there are no extended discussions of clashes between national laws, nor ‘cases [in which] a court must apply a foreign law’, in Classical Roman juristic texts.Footnote ²⁷ There is, however, an explicit discourse in both extra-legal and legal Roman texts acknowledging ‘overlapping spheres’ and entangled norms within Roman private law.Footnote ²⁸

Alongside the ius gentium (discussed by some Classical Roman jurists in relation to ‘natural law’), Babusiaux identifies three layers of Roman private law: the ius civile narrowly understood (the law of the citizen-body of Rome); the ius praetorium or ius honorarium (the law of the urban praetor – the praetor with jurisdiction between Roman citizens); and ‘imperial law’ (law enacted by or on behalf of the Roman emperors).Footnote ²⁹ Through a series of detailed case studies, Babusiaux convincingly demonstrates how the application of these different layers of law to specific legal questions could seemingly create clashes, requiring conflicting legal outcomes. The Roman jurist’s solution was not to rank the layers of law within an abstract hierarchy of precedence, but rather to reason out their application case by case:

The structuring of the different layers of (Roman) law was thus case-specific and dependent on the specialized reasoning techniques of the jurists themselves. In one sense, then, these Roman layers of law can be said to have operated heterarchically: side by side without the presumptive authority of one over the other. Yet the crucial point here is that it was the Roman jurists, the expert legal actors, who provided the overall structure by reasoning out potential overlaps, entanglements and clashes casuistically.Footnote ³¹

As I argue in Section 13.2, ‘postnational’ law’s focus on legal norms and principles is itself influenced by a modern (Western) tradition: a tradition that links normative-conceptual approaches to ‘defining what law is’ with territorial approaches to defining nation state sovereignty.Footnote ³² Rather than locating multiplicity and plurality in different bodies of overlapping and entangled norms and then positing ‘a set of new types of norms at the interfaces between different legal sub-orders’, Babusiaux’s analysis suggests that we should look to legal actors – in this case the Roman jurists – as structuring agents in their own right. As I suggest in Section 13.3 through a case study of the record of a protracted sixth-century CE dispute, this focus on legal actors as structuring agents is not simply a question of how different individuals and groups apply legal norms and principles in different times, places and contexts. Rather than adopting a modern ‘law in action’ or ‘law in practice’ perspective, Section 13.3 aims to develop an approach to norms and legal actors that is more akin to Lévi-Strauss’ disentanglements of Amerindian myths: ‘We thus do not pretend to show how men think in myths, but how myths are thought in men, and without their knowledge.’Footnote ³³

13.2 Beyond ‘Norms’ and the Nation State

From the later twentieth century onwards, jurisprudential attempts to define ‘what law is’ have become increasingly concerned with the normative-conceptual boundaries of legal ‘systems’, as opposed to the territorial boundaries of sovereign (nation) states.Footnote ³⁵ As Michael Guidice stated in his ‘think piece’ for the Geneva 2019 meeting, with reference to H. L. A. Hart, Hans Kelsen and Joseph Raz: ‘The concept of a legal system makes it possible to conceive of the membership of all norms within some domain.’ Defining a legal system primarily in terms of the norms that it ‘contains’, in turn, enables the idea of ‘norm interaction’ across all levels of ordering. Defining the boundaries of legal systems in terms of norms and rules thus opens up space to identify pluralist legal orderings, operating within and beyond the ‘conventional, and conventionally separate, structures of constitutional law (considered as the law of the Keynesian-Westphalian state) and international law (considered as the law between Keynesian-Westphalian states)’.Footnote ³⁶ According to Nico Krisch, ‘The resulting “postnational law” is thus a frame comprised of different orders and their norms.’Footnote ³⁷ Norms which, as we saw in Section 13.1, exist in heterarchical – rather than hierarchical – relation to each other. Hence one of the central claims of Krisch’s ‘postnational law’ paradigm: ‘that global law fares better if it embraces plurality, rather than trying to tame it in an institutional model’.Footnote ³⁸

To a historian whose research interests lie mainly within the presovereigntist, prenationalist and prepositivist world, the centrality of norms within ‘postnational law’ and the ‘Entangled Legalities’ project seems striking. Not only is the ‘frame’ of postnational law made up of orders which in turn are made up of norms, but the mechanism through which norm interaction is seen to take place is defined as a set of new types of norms, operating at the interfaces between different legal suborders. This set of new types of norms includes ‘reception norms’: ‘the typical form through which a legal system deals with norms from the outside; they reproduce the inside/outside distinction and define the ways in which outside norms enter a given body of norms’ (also referred to as between systems/conflict-of-law norms); ‘overarching norms’ which ‘regulate relations centrally and with binding character for the different bodies of norms involved’ (also referred to as within system/intra-systemic norms); and ‘connecting norms’ and ‘straddling pactices’, the ‘norms and practices that straddle different bodies of norms without being seen to belong to either, thus blurring the boundaries between them’ (‘straddling boundaries’).Footnote ³⁹ Norms have a ‘travelling content’ through which they perform their operations, becoming entangled within a broader discursive context:

The explicit focus here is on postnational governance structures and dispute resolution; nonetheless, using norms (and rules) as the primary tools for identifying and framing legal systems is very much part of a modern, ‘Keynesian-Westphalian’, state-sovereigntist, framework. As Roth-Isigkeit states: ‘the legitimacy of norm creation seems one of the most important achievements of the national state’.Footnote ⁴¹ What might appear (to ‘us’) as natural and timeless features of ‘strong’ legal norms and rules – their binding quality, their normativity, their legitimacy – have in fact been created through modern processes of nation state formation. With its main focus on legal norms – even entangled ones – the ‘Entangled Legalities’ project does not move us much beyond the (national) state. The fact that the project also includes some analysis of ‘weaker’ (‘informal, unenforced’) entangled norms, however, does potentially open up the field to much broader, legal pluralist, perspectives.

The idea that ‘strong’ legal norms have a jurisdictional aspect is central to both the state-sovereigntist and the postnational-pluralist ‘normativisation’ (Durchnormierung) of law:

The modern (Western) idea that every legal rule carries with it a ‘ticket’ to institutionalized enforcement links back to the presumption, discussed in Section 13.1, that law is only meaningful when backed by state power or – to phrase it more loosely – when structured by a Lévi-Straussian ‘Rome’.

‘Law in action’ and ‘law in practice’ approaches tend to rely on this modern, Western, idea of legal norms and rules carrying a jurisprudential aspect. It is inherent, for example, in Neil MacCormick’s call for a ‘user-orientated understanding of norms’ and also in the wider context of his definition of law itself as an ‘institutional normative order’.Footnote ⁴³ It is implied in Lon Fuller’s ‘interaction theory of law’ which ascribes an active role to individuals within the ‘legal system’ through an analysis of their ‘interactional expectancies’ when engaging with ‘enacted law’ (i.e. law that is accompanied by an explicit ticket to institutionalized enforcement).Footnote ⁴⁴ In terms of the international legal sphere, the ‘Transnational Legal Process model’ relies on norms having a jurisdictional aspect, enabling it to move beyond a formalist concept of rules, in order to stress the role of ‘internalized obedience’ in developing ‘sets of normative practices’.Footnote ⁴⁵ Finally, the ‘Entangled Legalities’ project’s account of ‘norm entanglement’ – I would suggest – also relies on the idea of ‘strong’ legal norms from different origins carrying different jurisdictional ‘tickets’. It is precisely this jurisdictional aspect which prevents individual norms from becoming integrated – rather than entangled – through the (repeated, dynamic) ‘social interplay of actors’:

Nonetheless, the claim that norm entanglement is ‘a common state of affairs in the law’ downplays the fact that the ‘normativisation’ of law is itself the product of a Keynesian-Westphalian, state-sovereigntist, ‘political’ framework.Footnote ⁴⁶ Classical Roman jurists did not understand law (or legal order) as a system of binding, imperative norms. As the Roman legal historian José Luis Alonso Rodriguez states: ‘Legal positivism not only means identifying law with legislation tout court […] It means also the thorough normativisation (“Durchnormierung”) of the law, the construction of the entire legal system as a system of imperative, binding norms. Nothing can be more remote from the Roman legal experience in the late Republic and early Empire.’Footnote ⁴⁷

We saw in Section 13.1 that relations between the different layers of Roman law were dynamic and heterarchical: they depended on the skill of Roman jurists to reason out potential overlaps, entanglements and clashes on a case-by-case basis. Alonso Rodriguez continues: ‘Legal Positivism […] stems from the normative monopoly of the sovereign and the subjection of the jurisdiction to the law, as theorized in modern political thinking from Hobbes onwards. Such normative monopoly and jurisdictional subjection are alien to the Roman political theory and practice of the late Republic and early Empire.’Footnote ⁴⁸ In other words, Roman legal norms, rules and principles did not carry with them an automatic jurisprudential aspect: ‘a ticket to some person, agency, or institution’. Roman jurisdiction was not subjected to the law, but was accorded to specific individuals and groups. These individuals and groups ranged from the formal iurisdictio cum imperio of Roman magistrates and provincial governors, to the legal authority granted to arbitrators by contractual Roman arbitration agreements, to the auctoritas exercised by jurists on account of their technical expertise, to the authority of a Christian bishop, a freelancing ‘holy man’, an Arab tribal leader, or any other local ‘big man’, recognized by two parties jointly seeking a (negotiated, mediated or adjudicated) resolution to a dispute.

Legal norms, then, did not define a Roman legal system any more than they defined a Late Antique Talmudic or early Christian legal order. My argument in Section 13.3 is not that legal norms, rules and principles were irrelevant to entangled legalities in Late Antiquity. Rather, I am suggesting that if we place the emphasis on Roman legal norms, we risk importing a modern jurisprudential aspect to them; and this would be at the expense of neglecting the plurality of entangled legalities that operated, in practice, through concrete appeals to multiple, different, types of power. Section 13.3 thus emphasizes the construction of legalities – plural – on the ground and, more specifically, the juris(dictional)-generative practices revealed in one sixth-century CE document: P. Petra IV.39, a report of proceedings before arbitrators from the Eastern (Byzantine) Roman Empire.Footnote ⁴⁹

13.3 Entangled Legalities: Beyond the (Byzantine) State

There is a history of Late Antique entangled legalities and juris(dictional)-generative practices yet to be written in which what went on in late Roman provinces is not simply labelled ‘provincial law’ or ‘provincial practice’ and seen to exist in a hierarchical relationship with laws and practices laid down by the imperial centre, but is instead conceptualized as a kind of heterarchical ordering in its own right. Most legal historians working today on the early Roman Empire (before 212 CE) would accept that its legal order was pluralistic: that there were multiple normative orders in operation on the ground, some of which were permitted, even encouraged, by the Roman state and some of which operated beyond it.Footnote ⁵¹ Whether this kind of legal pluralism persisted much beyond 212 CE – the date of the Emperor Caracalla’s grant of Roman citizenship to almost all (free) inhabitants of the Roman Empire – is more fiercely contested.Footnote ⁵² For our purposes, however, the interesting question is not whether legal pluralism existed within the Roman Empire between the fourth and early seventh centuries – it did – but rather what kinds of legal plurality and hybridity we are talking about.Footnote ⁵³ There is no reference in P. Petra IV.39 to formal Roman court proceedings or imperial bureaucratic legal officials.Footnote ⁵⁴ Instead, the legal actors mentioned in the document seem to have understood justice-seeking as an interconnected web of possibilities – making use of practical, localized and provisional (at least when viewed from beyond the relevant immediate time frame) – accommodations. As we shall see in the case of the multiple dispute settlements recorded in P. Petra IV.39, Late Antique legal entanglements could stretch across jurisdictional, religious and ethnic boundaries. Through an analysis of P. Petra IV.39 we thus move from pluralism ‘as a way an observer might see things from without – to pluralities: to seeing the world as experienced by those who inhabited it’.Footnote ⁵⁵

Since the 1950s, a wealth of new sixth- and early seventh-century documentary evidence has opened up the field of Late Antique juristic papyrology – the study of law through mainly documentary evidence recorded on papyri – beyond the large mass of texts recovered from Egypt.Footnote ⁵⁶ The American Center of Oriental Research in Amman, Jordan, has recently coordinated the publication of a remarkable five-volume set of papyri from sixth-century Petra, the remotely located metropolis of the Roman border province Palaestina Tertia.Footnote ⁵⁷ The papyri were found in December 1993, as part of ongoing excavations of the Byzantine Church of the Virgin Mary in Petra led by the American Center of Oriental Research. Two teams of papyrologists – an American team from Michigan University and a Finnish team from Helsinki – worked with around 140 carbonized rolls, reconstructing the private papers of a certain Theodoros, son of Obodianos (born 514 CE and died 591 CE), a property owner, deacon and later archdeacon of the Christian Church of the Virgin Mary in Petra (the location where the papyrus rolls were found).Footnote ⁵⁸ Taken as a whole, the Petra archive provides evidence for the persistence of Roman forms and structures in the city of Petra and its surrounding localities: there was a continued Roman military presence and the centralized land-tax system of the Byzantine Empire was still being implemented up to at least the period of the Arab conquests (c.634–8 CE).Footnote ⁵⁹ Yet when read together with Late Antique papyri from Egypt, in addition to other papyri from the Near East, the Petra archive does not reveal an Eastern Provincial law: ‘a hybrid, indigenous law of the Near East’.Footnote ⁶⁰ Instead, we see a series of concrete situations in which individuals and groups around and beyond the Late Antique eastern Mediterranean – Syria, Palestine, the Arabian Peninsula and Egypt – made use of numerous, entangled, legal practices, forms of argument and juris(dictional)-generative situations in order to get things done.

P. Petra IV.39 is a complex and incomplete text, reconstructed from around 3,000 fragments of papyri by its editor Maarit Kaimio and others. The document is a report of proceedings before arbitrators (dikastai), probably drawn up on 8 August 574 CE by an official notary from the Kastron Zadakathon (Sadaqa), a garrisoned, fortified settlement 20 km south of Petra on the margins of the Eastern Roman Empire. The reconstituted papyrus’ extant length is a remarkable c.6.2–6.5 metres, with 523 lines of text surviving. Nine different hands can be distinguished in the document, with one clear cursive hand indicating a trained scribe.Footnote ⁶¹ The document itself is written in Greek, but its contents reveal a multilingual environment. At certain points the papyrus refers to two languages being used simultaneously: Greek and ‘Syriac’ (probably an Aramaic dialect).Footnote ⁶² Both of the parties involved in the 574 CE dispute – Theodoros, son of Obodianos, and Stephanos, son of Leontius – are clergymen; as is Heiros, son of Thomallos, who drafted the arbitration agreement’s stipulation of penalty, and one of the arbitrators, Theodoros, son of Alpheios who is identified in the document as an archdeacon. The other arbitrator, Flavius Thomas, son of Boethos, was a senior officer in the local military unit garrisoned at Sadaqa.Footnote ⁶³ As discussed in more detail later in this section, the record of the 574 CE arbitration settlement refers to two previously negotiated settlements: one probably from the 530s, decided by an Arab tribal leader and a further settlement from sometime before 574 CE that had been mediated by a Christian cleric from a neighbouring rural area. In addition to arbitration and mediation proceedings, P. Petra IV.39 also refers to other forms of justice-seeking, which include trips to the ‘sacred shrine of the holy and glorious martyr Kerykos’ (in Sadaqa) in order to swear oaths of innocence on the Christian Holy Scriptures.Footnote ⁶⁴

The report of proceedings given in P. Petra IV.39 touches upon numerous points of dispute, all related to the fact that Theodoros son of Obodianos and Stephanos son of Leontius owned neighbouring properties in Sadaqa, as had their fathers before them. Theodoros and his father, however, seem to have been absentee property owners; at line 103 in the text Theodoros responds indignantly to an accusation that he does not ‘care for local matters’. Stephanos, on the other hand, seems to have taken advantage of Theodoros’ absence from Sadaqa in order to build new physical structures and make alterations to the flow of the water supply without Theodoros’ approval.Footnote ⁶⁵ This led to disputes over Stephanos’ and Theodoros’ rights to the water that drained from a roof-spout, which had originally been constructed by Theodoros and was the subject of an earlier dispute mediated by the ‘country bishop’ Sergios.Footnote ⁶⁶ Who owned which parts of the adjacent properties was also at issue, including rights of access across a central courtyard and rights of ownership relating to a refuse pit and an outbuilding.Footnote ⁶⁷ Theodoros claimed that the outbuilding was his by right of inheritance, producing a written deed of sale made for his father seventy years ago.Footnote ⁶⁸ He also seems to claim that he had been sold the outbuilding by two other individuals (Kassisaios and Gregoria), but could not produce any supporting written documents. Stephanos, meanwhile, counter-claimed that his father had bought the outbuilding and surrounding courtyard fifty-three years ago, apparently from Theodoros’ father. Stephanos produced two deeds of sale, but Theodoros responded that the outbuilding and surrounding land had not been included in the transaction. Added to this complex situation, P. Petra IV.39 also includes accusations of encroachment and theft of building materials – timber, blocks of stone and doors – by local soldiers, possibly under the command of one of the 574 CE arbitrators: Flavius Thomas.Footnote ⁶⁹ In addition, the document records a further, rather murky, claim for two solidi (gold coins) related to an earlier dispute between the families over a vineyard.Footnote ⁷⁰ Perhaps unsurprisingly, the hostilities between the two families spilled out into the local community, with Stephanos accusing Theodoros of deliberately stirring things up with the neighbours – who, we are told, made many ‘unwritten accusations’.Footnote ⁷¹ P. Petra IV.39 thus records a longstanding series of disputes between two local families, spanning several decades. There is obviously a complex backstory to the 574 CE arbitration. As a 546/7 CE papyrus from the Egyptian city of Antinoe put it, ‘many words have been said and many moves have been made’ before the parties brought their case before the arbitrators.Footnote ⁷²

Arbitration (and mediation), in contrast to judicial settlement by a standing tribunal, is designed by the parties to the dispute. The basic modern ‘principle of party autonomy’ – that the parties agree which issue(s) to submit to arbitration, that is, the issues to be decided upon; the choice of arbitrator(s); and the ‘applicable law’, that is, the law applicable to the dispute, including soft law and ‘non-binding’ law – can also be seen in operation in Roman arbitration proceedings. Similarly, the modern distinction between ‘ad hoc arbitration’ and ‘institutional arbitration’ (where the parties rely on the procedural rules of an arbitral institution determined by the relevant institution) can also be seen in Late Antique contexts. Arbitrations and other negotiation settlements before Late Antique Christian bishops and clerics, for example, developed institutionally specific norms and practices. Records of proceedings held before arbitrators and formal arbitration agreements survive on papyri from both the Late Antique Near East and the West. These include an Egyptian record of a dispute settled by arbitration in 647 CE and recorded in Coptic, which the editor of P. Petra IV.39, Maarit Kaimio, notes as the closest parallel to our 574 CE text. P. Petra IV.39, however, is unique in that it refers to the submission of written pleas and documents at an early stage of the proceedings, but records the parties’ oral pleas before the arbitrators in direct speech: ‘the speech flows in personal style, often becoming agitated and even insulting’.Footnote ⁷³ In other words, aside from the opening and concluding formalities of the arbitration procedure and the stipulation of penalty, the language used by the parties is not formulaic. What we see recorded in P. Petra IV.39 is a localized culture of argumentation.

Chronologically, the earliest negotiated settlement mentioned in P. Petra IV.39 relates to the vineyard and the claim for two solidi. This dispute, the papyrus states, occurred sometime in the past – Kaimio suggests the late 520s or 530s – between Theodoros, son of Obodianos and Leontius, the father of Stephanos. It was resolved before a mediator referred to in the document as ‘Abou Cherebos’. This is probably Abu Karib ibn Jabala, part of the Jafnid dynasty that acted as power brokers between Rome and the Bedouin.Footnote ⁷⁴ Abu Karib ibn Jabala was granted the Phylarcate of Palestine (including southern Jordan and Petra) by the Roman Emperor Justinian sometime in the 530s.Footnote ⁷⁵ Thus we have a relatively minor dispute over a vineyard, involving two landowners of middling means, mediated by an Arab tribal leader with a network of contacts that stretched all the way from (present-day) Jordan to the Emperor in Constantinople.Footnote ⁷⁶ In choosing Abu Karib as the mediator of their dispute, Theodoros and Leontius deliberately exploited local and imperial networks. The second negotiated settlement mentioned in P. Petra IV.39 took place sometime before 574 and was concluded between Theodoros, son of Obodianos, and the individual whom he claimed to have bought the disputed outbuilding from: a certain Kassisaios. The memorandum of this agreement, included in the documents submitted to the 574 CE arbitrators, states that it was made through ‘Sergios, priest and “country-bishop” (chorepiscopos)’.Footnote ⁷⁷ Here we have the parties appealing to a Christian cleric from a neighbouring rural area, perhaps either exploiting a personal network or, conversely, attempting to remove the dispute from its immediate, urban, context. We also see the use of a Christian cleric as arbitrator in the 574 CE settlement itself, alongside a high-ranking military officer who may have been directly implicated in the circumstances of the case. P. Petra IV.39 thus presents us with multiple justice-seeking attempts, before multiple individuals of different types. The crucial point to note here is that each of the different venues for dispute resolution were put into relation with each other by the parties to the disputes themselves. The interlinkage here is literally created through the parties’ own juris(dictional)-generative practices.

We turn, finally, to the legal norms and principles that the parties rely upon in their justice-seeking activities. In common with other papyri in the Petra and Nessana archives, the protocol of P. Petra IV.39 seems to make use of procedural terms and concepts derived from Roman law: ‘Instances of such terms in the text demonstrate beyond doubt that the parties and arbitrators had some, considerable, specific legal knowledge.’Footnote ⁷⁸ Marzena Wojtczak’s careful and cautious reconstruction of the substantive Roman rules and concepts that can be pieced together from P. Petra IV.39 also suggests the use of legal norms and concepts derived from Roman law, while at the same time highlighting the specificity of localized practices.Footnote ⁷⁹ According to Wojtczak, P. Petra IV.39 ‘gives an impression that we are actually dealing with a sequence of debts and securities between the two families’, involving ‘a sequence of fiduciary or fictitious sales’ with multiple ownership changes over a relatively short period of time (what a modern lawyer might refer to as a situation of relational contracting).Footnote ⁸⁰ As Wojtczak’s article concludes: ‘It should be considered that ordinary people, not acquainted with dogmatic legal patterns, sought solutions which would appear to protect their rights in [the] best possible manner. Transfer of ownership treated as a security for credit seems to be in accord with this idea.’Footnote ⁸¹

The use of a technical Roman legal register in P. Petra IV.39 thus needs to be understood within the context of local relations and localized practices. Evidence for these localized practices can be difficult to pinpoint in Late Antique legal and documentary source material, nonetheless, as Wojtczak’s example of the creative, ‘localized’ use of multiple fiduciary or fictitious sales suggests, Roman legal concepts and practices were put to work differently, by different networks of individuals, families and groups, operating within different localities around the empire. Moreover, the fact that this creative use of Roman legal norms in P. Petra IV.39 is apparent across a succession of settlements, decided in turn by Christian clerics, a Roman military official and an Arab tribal leader, underscores the fact that the Roman legal norms themselves were considered ‘portable’. Once again, there may be modern parallels to be teased out here in terms of exploring the relationship between entangled legalities on the ground and ‘strategic legal argumentation’. For example, Adam Bower stresses the role played by ‘strategic legal argumentation’ in contemporary multilateral settings: ‘First, in multilateral settings actors will tend to invoke justifications based in legal principles, norms, and rules – potentially in conjunction with coercive efforts – in pursuing policy goals. This strategy is preferable even when the actor making a claim does not fully endorse the standards it employs.’Footnote ⁸² Strategic legal argumentation, I would suggest, is at least as important as (‘travelling’) legal norms when it comes to the construction of entangled legalities past and present.

While it may be tempting to interpret P. Petra IV.39, and the Petra archive more generally, as evidence for the persistence of Roman forms and structures (the Roman military, the Roman land ownership and taxation system, Roman legal norms and principles), this would risk sidelining the situated, entangled web of practices that I discuss in this chapter. The fact that Roman legal norms underpin some of the parties’ direct speech as recorded in P. Petra IV.39 is an important point, but Roman law should not be understood as ‘the’ centralizing, organizing, principle at work across the life of these disputes. What P. Petra IV.39 suggests instead is a complex picture of connected localisms: Roman military networks are enmeshed within civilian, urban, life; Arab tribal leaders mediate property disputes between Christian clerics; and urban clerical networks intersect with wider rural connections. To reduce this connectivity to a static (Roman) provincial law would in fact sideline the extent to which Roman legal norms were put to work, by the parties themselves, in concrete situations and contexts. P. Petra IV.39 shows us sixth-century legal actors operating at the margins of empire, mobilizing multiple networks and regimes – local, regional, trans-regional, imperial – and in the process creating connected, but crucially not integrated, legal orderings of their own.

13.4 Conclusion

With our analysis of the presovereigntist, prenationalist and prepositivist world of P. Petra IV.39 we have moved far beyond a modern, state-sovereigntist, court-centric framework. P. Petra IV.39, in contrast, underscores the central role of legal actors in creating localized and entangled legalities on the ground; entangled legalities within which arguments from – portable – Roman legal norms and principles play a significant, but not determinate, role. One of the central questions posed by the ‘Entangled Legalities’ project is how to reimagine the global legal order through the paradigm of entangled legalities. I would argue that one answer involves reframing the analysis so that it shifts from a predominate concern with legal norms towards a ‘user theory of jurisdiction’: an analysis of the ways in which different legal actors shape themselves to the jurisdictional claims made by state, non-state and extra-state authorities and, in turn, work to shape the concept of jurisdiction itself. As Nico Krisch states: ‘the systemic, hierarchical and exclusive [image of law] may well constitute the exception rather than the rule’.Footnote ⁸³
