In a short article in the Zeitschrift für Numismatik for 1887, entitled ‘Die fünfzehn Münzstatten der fünfzehn diocletianischen Diöcesen’, Mommsen drew attention to what he considered to be a parallelism confirming his conclusions on the date of the Laterculus Veronensis and the origins of the diocesan system. It was not, in its details at least, one of his more distinguished contributions, and its shortcomings were mercilessly exposed by Mispoulet in a communication to the Académie des Inscriptions et Belles-Lettres in 1908. Mispoulet's verdict—that no parallelism between mint and diocese had existed under Diocletian, and was indeed not to be expected—was accepted by Seston in 1946 in his monograph on Diocletian and the tetrarchy, and despite the occasional subsequent comment implying limited support for Mommsen this verdict seems to have won general acceptance.

15 The much reduced province of Africa Proconsularis in which Carthage itself stood was of course not subject to the vicarius Africae (nor to the praetorian prefects for that matter) but to its proconsul, the vicar being, in theory at least, forbidden entry (e.g. CTh. 1, 15, 10). This would not inhibit the use of its mint by both and, since many of the laws in CTh. addressed to the vicar were (where recorded) accepted or posted at Carthage, he must in fact have been as frequently resident there. The administrative boundaries of both res summa and res privata remained unaffected by this anomaly: see below and, for the position of proconsuls, Jones LRE III, 5 (n. 17). The situation seems to have had much in common with that existing between the praefectus and the vicarius urbis (Romae).

21 According to Aurelius Victor (Lib. de Caes. 40, 17) Alexander was ‘apud Poenos pro praefecto gerens’. He was thus vicarius Africae. This is confirmed by Zosimus (Hist. II, 12), who adds that Maxentius had demanded that Alexander send his son to him as hostage, for fear that he would otherwise revolt. The closure of the mint of Carthage is further evidence of this attitude. For the reign of Alexander see, in the last instance, R. Andreotti in Afrika und Rom in der Antike (edd. H.-J. Diesner, H. Barth, H.-D. Zimmerman, 1968), 245–76. Sutherland (RIC VI, 411) emphasizes the extraordinary nature of the mint of Carthage. Certainly it was set up either shortly before or shortly after Maximian's arrival on campaign against the Quinquegentiani (297–8), and it consistently used variant designs on its products. But its continuance until 307 argues the fulfilment of more permanent needs. Seston (op. cit. 116–7) is sceptical of the military necessity for Maximian's visit, but (325–31) supposes several of the administrative rearrangements of the period to have resulted from it. This is not incompatible with what has been suggested of the mint.

It is over the longer term that the continuity of these mints becomes apparent.

35 Seston's proposed dating was 297/98 (op. cit. 333). But T. Flavius Postumius Titianus can be shown to have held the posts of both corr. Campaniae and corr. Italiae reg. Transpadanae before his ordinary consulship in 301 and his proconsulship of Africa in 295. See Chastagnol, op. cit. 21–5, where a date of 290/91 is suggested.

47 Constantius possessed a defined territorial jurisdiction: it remains uncertain whether Galerius did. The documentary evidence seems negative, although his extensive building operations in Thessalonica might be taken as implying the opposite. The coinage argues for the kind of administrative distinction between Constantius and Maximian that may have derived from the former's possession of his own chief rationalis as well as his prefect; cf. Jones, LRE III, 3 (n. 7), 6 (n. 24).

53 Although it is noticeable that the provisions of a procedural reform of Valentinian and Valens, resulting in the minting of precious metal being confined to the comitatensian largitiones, seem subsequently to have been relaxed to allow minting at prefectural headquarters—even if it was performed only by moneyers seconded for the purpose.

V. in JRS XLIX (1959), 46–55, and LIII (1963), 14–20.Google Scholar Propaganda on Roman coinage can, at best, never have been more than a secondary consideration. To the extent that the production of coinage was not primarily geared to the needs of the general public it was equally not so for its propagandizing. It was precisely those denominations that were least liable to (socially) wide, rapid circulation (i.e. gold and silver) that had the most rapidly changing design.

57 The military establishment in Africa was considerably increased at this period, probably as a result of Maximian's visit. But it could, even so, not compare with that of the Rhine, Danube or East. And it should be pointed out that Africa had, in fact, originally been provided with a mint—its closure being due to political reasons (cf. n. 21 above). The establishments in Spain and Viennensis seem to have been minimal. D. van Berchem, L'armée de Dioclétien et la réforme constantinienne 37–49 (Africa); Jones, LRE in, 374 (table IX, Africa), 379 (table XIV Africa), 377 (table XI, Spain and Tingitania). A large proportion of the African military seem to have been tribal limitanei (Jones, LRE III, 201, nn. 103–4, 106). For the Diocletianic calculation (and presumably payment) of military stipendia and donativa etc. in denarii (i.e. copper coin) see P. Beatty Panop. 2. For commentaries: ed. Skeat xxvi-xxx; Jones, LRE III, 187–9 (n. 31). For a Constantinian example: P. Oxy. 1047.
58 On the developed theory of the comitatensian (and therefore ‘travelling’) mint for the production of precious-metal coinage at this period, see: Bruun, P. M., Studies in Constantinian Chronology (1961), 23–77Google Scholar, and RIC VII, 13–8; Alföldi, M. R., Die constantinische Goldprägung (1963), 12–20Google Scholar. For a more sceptical view: P. Bastien's review of RIC VII in JRS LVIII (1968), 281; and, for Diocletian, Sutherland, RIC VI, 54–5. While a strong tendency towards a comitatensian pattern is undeniable, even at this stage, its elevation into a virtually exclusive rule is unwarranted—and is moreover disproved by fourth-century accessional and quinquennial issues. It was only with the measures described in n. 53 above that the regular existence of comitatensian mints such as Milan and Ravenna, which were both outside the earlier structure and which produced coinages that were virtually confined to the precious metals, was rendered possible.
59 Of the new mints Trier was the main residence of Constantius, Nicomedia that of Diocletian, and Thessalonica probably that of Galerius. The presence of a ruler at these mint cities doubtless influenced even their production of copper coin, but that it was not the predominant influence is seen by their continuing in production not only in the absence—often prolonged—of the ruler, but also into periods when they were no longer residences.
