Seius

1. M. Seius L. F., distinguished himself by his largesses to the people in his curule aedileship, although he had been previously condemned to the payment of so great a fine that he had no longer sufficient property to entitle him to a place in the equestrian census. We do not know the year in which he was aedile; but Cicero says that he was elected in preference to M. Pupius' Piso, who was consul in B. C. 61 (Plin. Nat. 15.1; Cic. de Off. 2.17, pro Planc. 5). In B. C. 52 he accused M. Saufeius, who was defended by Cicero [Saufeius, No. 2]. In the following year, B. C. 51, he was involved in the condemnation of Plaetorius (incendio Plaetoriano ambustus, Cic. Att. 5.20.8). [Plaetorius, No. 5.] He was a friend of Atticus and Cicero, and the latter laments his death in B. C. 45. (Ascon. in Milon. p. 55, ed. Orelli; Varr. R. R. 3.2.7, 3.10.1; Cic. Fam. 9.7, ad Att. 5.13, 12.11.)

Seius

2. M. Seius, probably the son of the preceding, was a friend, and apparently legatus, of D. Brutus, in B. C. 44. (Cic. Fam. 11.7.)

Seius

3. Seius, was a partisan of M. Antonius, after the death of Caesar, and is therefore abused by Cicero (Cic. Phil. 12.6). The person called Viseius in another passage of Cicero (Cic. Phil. 13.12), is probably a false reading for Seius.

Seius

4. Cn. Seius, had the finest horse of his age, which was fated to bring destruction to whoever possessed it. Seius was condemned and put to death by M. Antonius, afterwards the triumvir, apparently during the civil war between Caesar and the Pompeians. This horse then passed into the hands of Dolabella, and afterwards into those of Cassius, both of whom perished by a violent death. Hence arose the proverb concerning an unfortunate man : ille homo habet equum Sejanum. (Gel. 3.9.)
