Hieroglyphics of Horapollo: Book II.: CII. How a Man Unable to Move Himself
Hieroglyphics of Horapollo, tr. Alexander Turner Cory, [1840]
When they would symbolise a man who for a long time is unable to move himself, but who afterwards moves with his feet, they depict A FROG HAVING ITS HIND FEET; for it is born without feet, but subsequently as it grows acquires its hind feet.
