Among the many problems besetting the study of Middle Byzantine economic history are those concerning adjustments to the partial demonetisation of transactions indicated by the fall-off in the numismatic record (of excavations, hoards, and stray finds) for the seventh to ninth centuries, and the origins of a subsequent remonetisation. The administrative systems through which the Middle Byzantine state met its various needs during this period, and the evolution of such systems in response to economic changes (often assumed to be of the state’s own making), have recently attracted attention, a development stimulated by the enrichment and re-ordering of the sigillographic record.

6. Antoniadis-Bibicou, ch. 5–6. The argumentation is unfortunately diffuse, but even the most detailed review of the work, by Lemerle (Revue Historique 232 [1964] 225–31) does not engage with this thesis.

For clear analyses of the Late Roman origins of the land-tax in kind and the logicality of its Middle Byzantine designation as (i.e., compulsory purchase: basically some of the techniques used for compulsory purchase were applied to the assessment and levying of the land-tax) see Stein, E., Histoire du Bas-Empire, II (Brussels 1949) 200–01 Google Scholar and Haldon, 229–32; for the importance of payment in kind in Late Antiquity and the difficulty of commutation, Hendy, 294–96 and 605–06; for other arguments supporting Middle Byzantine taxation in kind, Antoniadis-Bibicou, 189–99 and 255.

16. Zacos-Veglery, 135. For the ‘pre-indictional’ history of this institution see now Oikonomides (1986) 33–38, and for its specialist functions Oikonomides, Hendy, and Haldon as cited n.5. But Haldon evokes the complexity of such dealings in a demonetising economy, and logically deduces the role of the Apothekai in supplying the military’s many material needs (ibid., 239–41).
17. I follow Hendy, 626–45, regarding coin-usage; ibid., 409–14 and 628–29, on the breakup of the Praetorian Prefecture of the East. That part of the cursus publicus which dealt in taxes raised in kind was being abolished in the sixth century (ibid., 295–96). Haldon arrives at essentially similar conclusions regarding the breakup of the Prefecture (Haldon, 183–204), but also (loc. cit.) proposes that the Prefecture survived as a shadowy co-ordinator of the new fiscal departments with a sustained civil provincial administration, for the purpose of feeding and equipping the military. However the effective test of Middle Byzantine bureaucratic realities, the sigillographie record, now quite large, is negative. There are no seals of this Praetorian Prefect. The Praetorian Prefect of Illyricum becomes on his seal the ‘Eparkhos of Thessalonike’ (cf. Nesbitt-Oikonomides I, nos. 18.18–23), surviving until the constitution of the thema of Thessalonike, when he disappears. There are no other seals of the Eparkhoi of provinces in the E. Mediterranean orbit. An 8th-century Eparkhos of Nicaea is not the governor of a province (Zacos-Veglery, no. 3156), and seals of Eparkhoi without a geographical designation are invariably of Eparkhoi of Constantinople (e.g., Zacos II, no. 328), and anyway take us beyond our period of concern. Only one seal of an (the equivalent title) from our period of concern is to be found in the largest relevant collection (Zacos-Veglery, no. 701), but has no geographical designation, so may be of Constantinople. One seal of an Arkhon of Lydia (ibid., no. 1489: 7th c.) might fall within our period of concern. Haldon himself shows (op. cit., 204, n. 118 and 205, n. 120) that seals of Anthypatoi of the 7th to 9th centuries are, with two exceptions of the 9th century, not the seals of ‘proconsular’ civil provincial governors. We are therefore left with no group of seals attributable to civilian provincial governors for a notional Praetorian Prefect to co-ordinate in the mid 7th to mid 9th centuries. Admittedly this is negative argumentation and does not result in an alternative view regarding the existence or absence of civil governors. It is only meant to suggest that the titulature of a 9th-century courtly ceremony used to support the perpetuation of the Prefecture and civil governors (Haldon, 195 and 201), hence the perpetuation of an older set of arrangements for dealing with taxes and compulsory purchases in kind, receives as yet no sigillographie corroboration.
18. For seals of Dioiketai with a multi-provincial brief see Haldon 196–97. Seals of Dioiketai of named provinces are very scarce for the 7th century (e.g., Zacos-Veglery, nos. 1628 and 2290: probably mid to late 7th c.). The majority of seals of this period (mid 7th century onwards) are of ‘undesignated’ Dioiketai (e.g., Zacos-Veglery, nos. 616, 1439, 1464, 1527, 1528, 1534). There are more such seals of the 8th century.

30. However Oikonomides’s arguments about an empire-wide official commercialisation of silk from the imperial workshops and about far-flung mulberry-plantations in central and eastern Anatolia, Macedonia, and Thrace, in the 7th-9th cc., run into a mass of practical objections, depending upon the region, environmental, political, communicational … (see now Haldon as cited n.5).
31. In fact Oikonomides recognises (Oikonomides [1986] 45–46) that several indiction-dated seals referring to Apothekai/Kommerkia and to fiscal officials (Logothetai, Dioiketai) or their circumscriptions (Dioikeseis) should be the seals of tax-farmers (who are supposedly also purveying silks to their victims). And Haldon (as cited n.5) gives effect to Hendy’s model of the Kommerkiarios as supplier of equipment to the provincial regiments by linking defrayment of the costs to a system of taxation in kind and corvée.

58. Erythrai, whose name survived locally until this century as ‘Lythri’, had been important in the Roman period. It had a protected harbour, opposite Chios, but no hinterland of its own (RE VI, cols. 575–91). It was a suffragan of Ephesus throughout the Middle Byzantine period: Darrouzès, J., Notitiae episcopatuum ecclesiae constantinopolitanae (Paris 1981 Google Scholar) not. 1, 2, 3,4,7,9,10, and 13.

59. For Constantinople see R. Harrison, Excavations at Saraçhane I, ch. 12, ‘The coins’, by M. Hendy, particularly 278–80. The Apotheke of Constantinople, attested in the 7th to 8th cc. (Zacos-Veglery 1/I, Table 21) was perhaps where much primary produce taken in taxation was commercialised or otherwise exchanged. The only useful published coin-series from the older inner provinces, the 1,234 identifiable coins of the years 491–1282 AD from the excavations of Sardis of 1958–1968, indicate a slight revival of the petty currency from the time of Leo V (813–820) onwards, after a period (667–812 AD) for which there are only 5 coins: Bates, G., Archaeological exploration of Sardis.

61. The connection between the Kommerkiarioi and the needs of the military would be detectable to the end if a seal of a ‘Khartoularios and Kommerkiarios of Presthlavit-za’ (Nesbitt-Oikonomides I, no. 78.3) were a seal of a military Khartoularios (for seals of whom see Laurent II, nos. 554–78).

65. Of course there is the problem of the tendency within the élite towards the use of ‘private’ seals. But other high fiscal officials continued to advertise their functions on their seals (Pronoetai, Anagrapheis, Exisotai…), which is hardly surprising given the nature of their business.

89. This interpretation of the use in the ninth through eleventh centuries of the title ‘Kommerkiarios of the West’, combined or not with specific provinces, does not preclude other meanings for Dysis in other branches of the administration, fiscal and military, at these and other times.
