Plutarch, Sayings of Romans 206e
Caesar’s famous saying, as carried (in Latin) on placards in his triumphal procession. Plutarch gives a Greek version; Appian (Civil Wars 2.91) likewise says it was sent in a letter, while Dio Cassius (42.48) also alludes to it.
Φαρνάκην δὲ νικήσας τὸν Ποντικὸν ἐξ ἐφόδου πρὸς τοὺς φίλους ἔγραψεν· “ἦλθον, εἶδον, ἐνίκησα.”
After conquering Pharnaces of Pontus at the first assault, he wrote to his friends, ‘I came, I saw, I conquered.’
