Iphicrates on Vigilance

Iphicrates, the Athenian general, was holding Corinth with a garrison, and on the approach of their enemies, he himself was keeping watch. A guard was sleeping, so he pierced him through with a spear; some rebuked this act as though it were cruel, but he said, “As I found him, so I left him.”

Iphicrates, dux Atheniensium, cum praesidio Corinthum teneret et sub adventum hostium ipse vigilias circumiret, vigilem, quem dormientem invenerat, transfixit cuspide; quod factum quibusdam tamquam saevum increpantibus “qualem inveni”, inquit, “talem reliqui.”
