Note 1448 — PERSIUS.

Canthum. "The tire of the wheel." Quintilian (i., 5) says, "The word is of Spanish or African origin. Though Persius employs it as a word in common use." But Casaubon quotes Suidas, Eustathius, and the Etym. Mag., to prove it is a pure Greek word; κανθὸς, "the corner of the eye." Hence put for the orb of the eye.
