3. Cf. Sallust, Catilina 29.2–3Google Scholar, discussing the senatus consultum ultimum: “Itaque, quod plerumque in atroci negotio solet, senatus decrevit, darent operam consules, ne quid res publica detrimenti caperet. Ea potestas per senatum more Romano magistratui maxuma permittitur: exercitum parare, bellum gerere, coercere omnibus modis socios atque civis, domi militiaeque imperium atque iudicium summum habere; aliter sine populi iussu nullius earum rerum consuli ius est.” Consider, too, the extraordinary argument that erupted over the actions of Cnaeus Manlius Vulso in 187, when he sought a triumph for a victory won over the Galatians, but in a campaign not authorized by the “people” (Livy 38.45.3-7): “Cupientem transire Taurum aegre omnium legatorum precibus, ne carminibus Sibyllae praedictam superantibus terminos fatalis cladem experiri uellet, retentum, admovisse tamen exercitum et prope ipsis iugis ad diuortia aquarum castra posuisse. Cum ibi nullam belli causam inueniret quiescentibus regiis, circumegisse exercitum ad Gallograecos, cui nationi non ex senatus auctoritate, non populi iussu bellum inlatum. Quod quem umquam de sua sententia facere ausum? Antiochi, Philippi, Hannibalis et Poenorum recentissima bella esse; de omnibus his consultum senatum, populum iussisse, saepe legatos ante missos, res repetitas, postremo, qui bellum indicerent, missos. ‘Quid eorum, Cn. Manli, factum est, ut istud publicum populi Romani bellum et non tuum priuatum latrocinium ducamus?… “”

21. On the local, Latin origin of fetiales, see Dionysius 2.72.1-2, suggesting that Numa instituted them in imitation of Aequicoli or Ardea; he attributes the latter suggestion to Gnaeus Gellius (fr. 16 Peter). See also Livy 1.32.6 ([Ancus Marcius] “ius ab antiqua gente Aequiculis quod nunc fetiales habent descripsit”) and 14 (“Hoc tum modo ab Latinis repetitae res ac bellum indictum, moremque eum posteri acceperunt”). The currency of this legend in late-Republican Rome, in multiple forms, is further confirmed by the elogium to Fertor Erresius, an inscription found in the Roman Forum: “Fert. Erresius, rex Aequeicolus. Is preimus ius fetiale paravit; inde p. R. discipleinam excepit (Fertor Erresius, Aequicolan king. He first crafted the fetial law; thence the Roman people received that science)” (ILS 61). See also Cicero, Rep. 2.31Google Scholar; Plutarch, Numa 12.4–5Google Scholar; and Servius, Aen. 7.695Google Scholar. Note also how Livy sums up his account of the fetial ritual (1.32.14): “Hoc tum modo ab Latinis repetitae res ac bellum indictum, moremque eum posteri acceperunt.” For a late attempt to construe foreign behavior as analogous to fetial practice, see Ammianus 19.2.4-6, describing the assault on Amida of Grumbates and the Persians (where Ammianus himself was present): “(4) Cernentes populos tam indimensos ad orbis Romani incendium diu quaesitos in nostrum conversos exitium, salutis rata desperatione gloriosos vitae exitus deinde curabamus, iamque omnibus nobis optatos. (5) a sole itaque orto usque diei ultimum acies immobiles stabant ut fixae nullo variato vestigio nec sonitu vel equorum audito hinnitu, eademque figura digressi qua venerant, cibo recreati et somno, cum superesset exiguum noctis, aeneatorum clangore ductante urbem ut mox casuram terribili corona cinxerunt. (6) vixque ubi Grumbates hastam infectam sanguine ritu patrio nostrique more coniecerat fetialis, armis exercitus concrepans involat muros confestimque lacrimabilis belli turbo crudescit, rapido turmarum processu in procinctum alacritate omni tendentium, et contra acri intentaque occursatione nostrorum.”

24. I have argued elsewhere that the first two centuries C.E. witnessed a revolution in conceptions of cultural and political identity under the empire, in which subject populations first and Romans later broke down the citizen-alien distinction in favor of one that divided the world between those who lived inside and outside the empire (Ando, C., Imperial Ideology and Provincial Loyalty in the Roman Empire [Berkeley: University of California Press, 2000], 277–335)Google Scholar; and I take up these issues again in two studies charting the intertwined histories of the law of persons and of political subjectivity at Rome and in the provinces:“From Republic to Empire,” in The Oxford Handbook of Roman Social Relations, ed.
