Hieroglyphics of Horapollo, tr. Alexander Turner Cory, [1840], at sacred-texts.com
When they would symbolise a man who through want dismisses his own children, they portray A HAWK WITH EGG; for though she lays three eggs, she hatches and brings up but one, and breaks the other two: and she does this on account of the loss of her claws at that season, being for that reason unable to bring up all three young ones.
