Extract

One of Rome's greatest achievements was the successful enlistment of her conquered peoples for the defence of her empire. How much was Roman statesmanship willing to pay for this? Part of the answer lies in the dignity, freedom, and participation which Roman rule granted to these peoples. Another part of the answer will be found in the pay of the auxilia; for although they were recruited from among the subject nations they matched the legions in numbers, fighting spirit, and efficiency at integrating the provinces into the Empire.

The pay of the auxilia and its relation to the pay of the legions is a vexing problem which has elicited the ingenuity of many scholars. Recently, however, a new reading of the papyrus P. Gen. Lat. l and a newly-found inscription have increased the scanty evidence. They may now reveal at least part of the answer.

7 Mommsen suggested the 75 denarii were reckoned to equal 300 drachmae, but drachmae in billon, worth 6 obols each, i.e. 1,800 obols. But 1,800 obols, reconverted into silver drachmae, worth 7¼ obols apiece, result in 248 drachmae 3 obols, not the 247½ drachmae that P. Gen. Lat. 1 records.

8 This was maintained first by Th. Mommsen, l.c. (above, n. 6), and in the latest instance by Marichal, R., ‘La solde des armées romaines d'Auguste à Septime Sévère,’ Annales de l'Institut de Philologie et d'Histoire Orientales et Slaves 13 (1953), 339421Google Scholar; also by Fink, Records p. 245.

9 IGRR i, 1337 gives a long list of soldiers with tria nomina in the cohors I Hispanorum in A.D. 85, cf. Lesquier, , L'armée romaine d'Egypte (1918), 88Google Scholar, n. 5. Likewise, P. Oxy. 1022 of A.D. 103 (= Fink, Records 87) names six recruits of the cohors II or III Ituraeorum, all have the tria nomina. There are other similar cases.

10 The other four documents on P. Gen. Lat. 1 (= Fink, Records 9; 10; 37; 58) record men with tria nomina exclusively. As has been said, however, this does not prove P. Gen. Lat. 1 to refer to a legion. Fink (Records 9 and 58) assumes the verso to refer to Legio III Cyrenaica, yet conclusive proof is wanting. Even if it could be produced, nothing could be inferred for the recto, on which the pay-records were written some ten years later, for by then the verso was treated as waste paper, and was glued together and recycled (see Fink, Records p. 107). Legionary and auxiliary detachments often shared a camp, and thus might easily have used each other's ten-year-old waste paper.

Johnson's thesis was adopted by Passerini, A., Le coorti pretorie (1939), 101Google Scholar, n. 2 and Forni, G., Il reclutamento delle legioni da Augusto a Diocleziano (1952), 32 ff.Google Scholar

R., ‘The Pay of the Roman Army, Suetonius, Dio and the Quartum Stipendium,’ Historia 5 (1956), 332340Google Scholar, and in The Roman Soldier (1969), 104 ff. suggested such a difference, but Fink (Records p. 245) had rightly pointed out that if this were correct one would expect different sums to be retained at different times, since the expenses they covered varied greatly; also the text says clearly accepit stip(endium). Above all, Watson's thesis would force one to assume an unlikely basic change in book keeping between the date of P. Gen. Lat. 1 and P. Gen. Lat. 4.

(above, n. 12), 54. Brunt's own three-fifths thesis collapses with the new date (A.D. 192) for P. Berol. 6866, cf. Fink, Records 70.

Dura 100 and 101 show that vexillarius was not a permanent rank.

18 cf. Speidel, I.c. A cut in pay, as suggested by Breeze, I.c., would be totally unparalleled. A time of warfare certainly does not mean ‘abnormal conditions’ for a soldier of Domitian and Trajan, nor does this man's career (or any other) indicate that promotion prospects in the auxilia were better than in the legions. cf. the commentary to AE 1969–70, 583.

19 The demand of the Batavian cohorts in A.D. 69 for duplex stipendium (Tacitus, Hist. 4, 19) cannot be taken as a demand to double the auxiliary pay in general, nor, therefore, as evidence that it must have amounted to less than half the legionary pay, as Watson, l.c. (above, n. 12), 373, assumes; cf. also Brunt l.c. (above, n. 12), 64 f. It will rather have been a demand for some special favour similar to augeri equitum numerum: perhaps double pay for merit (cf. Dessau 9098, of the time of Septimius Severus), or wholesale promotion in the ranks. For duplicarius as a pay-grade encompassing several ranks, cf. Gilliam, J., ‘The Moesian Pridianum,’ in Hommages à A. Grenier (Collection Latomus 58, 1962), 747756Google Scholar and Fink, Records p. 16 f.

21 No pay-raise seems to have occurred during the second century A.D. before Septimius Severus. cf. Passerini, A., ‘Gli aumenti del soldo militare da Commodo a Massimino,’ Athenaeum 24 (1946), 145159.Google Scholar

22 In P. Beatty Panop. 2, 36 ff. and 291 ff. the stipendium of the cohorts amounts to twice their annona, the stipendium of the alae to three times their annona. If the annona was the same for both kinds of units, then their stipendium was in a relation of 2:3, which would fit better the two-thirds thesis. But perhaps the annona of the alae was higher, too, so that this ratio need not apply. Jones, A. H. M., The Later Roman Empire (1964) II, 623Google Scholar, commenting on this papyrus, assumes the pay of a miles legionis to equal the pay of an eques alae, and two-thirds of this to be the pay of a miles cohortis. His figures, however, are not meant to be more than hypothetical, because the number of men in each detachment or unit could vary widely. (E.g., the donatives for the alae could be the same as those for the legions; if so, the detachment of the ala II Herculiana dromedariorum in lines 168 ff. was 43 men strong rather than 211, which is not in itself impossible.)

25 We follow Watson's convincing proposition that the figures be divisible by 25 so as to be accountable in aurei as was the viaticum (in BGU ii, 423 and P. Berol 6866) and the legionary pay throughout. This assumption is now confirmed by the new figures for auxiliary pay: 7½ aurei before A.D. 84 and 10 aurei thereafter.

26 cf. Forni, I.c. (above, n. 11), 33. 25% of the recruits for the alae on Rhine and Danube were citizens by Trajan's and Hadrian's time, as is revealed with some precision by the number of equites singulares Augusti that do not change their names to that of the ruling Emperors, cf.
