1Hieroglyphics of Horapollo, tr. Alexander Turner Cory, [1840], at sacred-texts.com
When they would denote intrepidity, they depict a LION, for he has a great head, and fiery eyeballs, and a round
face, and about it hairs like rays in resemblance of the sun; and hence it is, that they place lions under the throne of Horus, intimating the connexion of the animal with the god. And the sun is called Horus from presiding over the Hours.
II. Lions supporting the sun in his resting place; from Thebes about the beginning of the 18th dynasty.
