Hieroglyphics of Horapollo, tr. Alexander Turner Cory, [1840], at sacred-texts.com
When they would symbolise a man who is impudent
and quicksighted, they depict A FROG; for it has no blood except in the eyes alone, and they call those who have blood in those parts impudent: and hence the poet sings, "Drunkard with eyes of dog and heart of stag."
