Kefalos
From Simon Online
Kefalos ichthys grece cefalus piscis mugilis.
Translation:
Greek Kefalos ichthys is in Latin cefalus piscis {lit. “the fish cefalus”}, or another Latin name for it is mugilis
Commentary:
Greek ἰχθῦς or ἰχθύς /ichthŷs/ or /ichthýs/ is the word for “fish”; and κέφαλος /képhalos/ is the name for a species of mullet; the word was adopted into late Latin as cephalus. Latin mugilis or mugil is a sea-fish, possibly the mullet.
