Coin Hoards and the Chronology of the Gallic Emperors
Published online by Cambridge University Press: 09 November 2011
Abstract
In the story of imperial Rome no period can be more obscure than that which elapsed between the death of Severus Alexander and the accession of Diocletian (235-84). Here the historian faces a dearth of reliable literary information. Inscriptions and papyri are also in short supply; and consequently recourse must be had to more controversial sources of knowledge—numismatics and archaeology. Thus problems abound. The very chronology of the age is still disputed; and in this dispute the question which continues to attract most attention is that relating to the dates of the so-called ‘Gallic emperors’ who governed an independent west, quite separate from Rome, during the middle years of the third century.

9 Although it must be said that even here his arguments are frequently very unhappy, e.g. in order to deprive Tetricus of an obvious, but for him very awkward, third consulship, he had to insist (1964, 113) that the coin legend TR P COS III should be read TR P III COS, a quite arbitrary transposition.

15 Tables II and III; cf. Lafaurie (1964), 119-27. Apart from variations in the actual hoards considered it will be seen that I have made other alterations to Lafaurie's format, e.g. by changing some of the column headings, by amalgamating the catalogue of groups and the list of hoards, and by adding a new set of figures showing the (approximate) percentage-composition of each find. All this should, I hope, make for the easier comprehension of the information presented.

20 As assumed by Lafaurie (1964), 103 f. In the same place, it should be noted, Lafaurie exhibits an alarming disregard for simple arithmetic. His guess that it would take about six months for the coins of Quintillus and Aurelian to reach Gaul and to be buried in hoards containing the late issues of Victorinus would put the end of the last's reign around the middle of 270, yet he advances this date inexorably and without explanation to the end of 270 and even the beginning of 271!

22 Compare the figures (mainly of antoniniani) from Silchester (Tetricus 632, Claudius/Quintillus 617, Gallienus 372, Victorinus 252, Postumus 70, Aurelian 16) and Alzey (Tetricus 52, Claudius/Quintillus 27, Gallienus 11, Victorinus 10, Postumus 2, Aurelian 1).

24 Thus in Britain the great Blackmoor hoard (NC 1877, 90-156) which included pieces of Allectus also comprised: Tetricus 14,028, Claudius/Quintillus 4,401, Gallienus 3,842, Victorinus 5,450, Postumus 399, Aurelian 189. (I have noticed that Claudius II is regularly less well represented in the hoards than in the site-finds—this would perhaps repay closer investigation.)
25 P. le Gentilhomme, ‘Variations du titre de l'antoninianus au IIIe s.’, RN 1962, 141-66.
26 This must surely put paid to Callu's (o.c. (note 13), 276) over-simple explanation of the currency of the period: ‘Au début du règne de Victorin, les antoniniani de Pcstume forment encore le gros de la masse courant. Ils tendent ensuite à disparáître du marche …’ (my emphasis).
27 The continued unpredictability of coin-circulation is revealed by the existence of hoards with ‘Lafaurie-characteristics’, i.e. a few pieces of Aurelian, several of Postumus, less of Victorinus, but which also contain some coins produced by Tetricus. By Lafaurie's hypothesis, i.c. by assuming smooth circulation, these ought to have been buried just at the beginning of Tetricus's reign. All, however, possess pieces of Tetricus II, who was created Caesar just before his father's fall (Elmer, op. cit. (note 2), 79 ff.), and one, Bourg Blanc (RN 1966, 181-98) contained a coin of Florian!
