A handbook of astrology seems an improbable source of information about Constantine's dealings with the Roman Senate. Yet if the work were contemporary, and if both author and addressee were senators, then a few passages might betray a hint of transactions either not otherwise attested or not elsewhere documented in any detail. Such is in fact the case with the Mathesis of Julius Firmicus Maternus Junior v.c., of which one passage in particular can be made to disclose specific facts of some historical importance. Maternus discusses the horoscope of a man, whose father was exiled after twice being ordinary consul, and whose own career advanced from exile to the urban prefecture of Rome. Neither is named; they were familiar to both the author and the addressee of his work.
1 Math, ii, 29, 20: ‘cuius haec genitura sit, Lolliane decus nostrum, optime nosti’. The horoscope received no discussion in Thorndike, L., ‘A Roman Astrologer as a Historical Source: Julius Firmicus Maternus’, CP viii (1913), 415–35Google Scholar.

3 Math, i, 10, 13: ‘dominus et Augustus noster ac totius orbis imperator pius felix providus princeps, Constantinus scilicet maximus divi Constantii filius augustae ac venerandae memoriae principis, qui … apud Naissum genitus a primo aetatis gradu imperii gubernacula retinens, quae prosperis nanctus fuerat auspiciis, Romanum orbem ad perennis felicitatis augmentum salubri gubernationis moderatione sustentat’. For the necessity of emendation, cf. F. Boll, RE vi, 2366. The fact that W. Kroll and F. Skutsch printed ‘divi Constantini’ occasionally misleads scholars (Teubner ed., i (1897), 37, cf. ii (1913), 547).

35 As does Chastagnol, o.c. (n. 30), 95: ‘Nous avons vu que Groag pense plutôt—avec raison, nous-semble-t-il—à Vettius Rufinus, préset en 315–16, et à son père homonyme. Dès lors tombe entièrement le raisonnement mathématique spécieux de O. Neugebauer.’

41 Kroll and Skutsch note: ‘sc. Sol de quo etiam sequentia solo dicuntur’ (edn. i (1897), 82).
42 The addition of ‘et’ is due to E. Badian (verbally, on 21 February 1974). Elsewhere in his discussion, Maternus consistently uses ‘ipse’ to distinguish the son from the father: ‘eius geniturae pater …, sed et ipse’ (10), ‘patrem … de ipso’ (11), ‘et ipsi et patri eius exicitavit inimicos’ (12), ‘ipsum vero’ (14).

89 Probably late spring 326, cf. MGH, Auct. Ant. ix, 232. The circumstances remain obscure. A recent writer asserts that ‘the significant fact is that Crispus was illegitimate’ (Guthrie, P., Phoenix xx (1966), 325CrossRefGoogle Scholar). But the earliest allusion to his mother (in 307) uses the word ‘matrimonium’ (Pan. Lat. vii (vi), 4, 1).
