Lydus quotes a Capito three times, a Fonteius four times, Capito and Fonteius together twice, and adds that they were contemporaries of Varro and Sallust. He calls Capito a ἱερεύς, makes him an interpreter of the Etruscan Tages, and attributes a few oracles to him as well as some calendary matter. He calls Fonteius a ῾Ρωμαῖος, refers to his oracles, his interpretation of the Etruscan discipline and his work περὶ ἀγαλμάτων, and gives his ‘Tonitruale’ in Greek translation. Modern scholars identify Capito with the antiquarian Sinnius or the jurist Ateius Capito, and they assign Fonteius to the imperial period but leave him unidentified. There is nothing in the texts to support these suggestions. My conjecture is that we have to deal with one man, C. Fonteius Capito, who was ‘ad unguem factus homo, Antoni, non ut magis alter, amicus’ (Hor. Sat. 1, 5, 32 f.). Born c. 80, he became pontifex apparently after 44, when, with the help of Antony, Lepidus was elected pontifex maximus. He soon received another office from Antony—according to Groag that of a tribune—and went with him to the East. These facts emerge from an (unpublished) inscription from Cos, of c. 39, which calls him a ἱερεύς and records that, on his request, the rule of Antony was accepted on Cos.
