Paetus
A cognomen in many Roman gentes; it signified a person who had a slight cast in the eye. This was regarded by the Romans as giving piquancy to beauty, and was ascribed by them to Venus, as in the line from the Priapea:“Minerva flavo lumine est, Venus paeto”
which explains the passage in Horace ( Sat. i. 3, 45), where the fond father calls his squinting son paetus, i. e. “Venus-eyed.”
