Plutarch
The Conception of Anubis
They relate also that Isis, learning that Osiris in his love had consorted with her sister through ignorance, in the belief that she was Isis, and seeing the proof of this in the garland of melilote which he had left with Nephthys, sought to find the child; for the mother, immediately after its birth, had exposed it because of her fear of Typhon. And when the child had been found, after great toil and trouble, with the help of dogs which led Isis to it, it was brought up and became her guardian and attendant, receiving the name of Anubis, and it is said to protect the gods just as dogs protect men. – 356f
Hermes and Anubis Equated
The facts are that they do not call the dog by the name Hermes as his proper name, but they bring into association with the most astute of their gods that animal’s watchfulness and wakefulness and wisdom, since he distinguishes between what is friendly and what is hostile by his knowledge of the one and his ignorance of the other, as Plato (Republic, 375 E) remarks. – 355b
Anubis’ Parentage and Powers
When Nephthys gave birth to Anubis, Isis treated the child as if it were her own; for Nephthys is that which is beneath the earth and invisible, Isis that which is above the earth and visible; and the circle which touches these, called the horizon, being common to both, has received the name Anubis, and is represented in form like a dog; for the dog can see with his eyes both by night and by day alike. And among Egyptians Anubis is thought to possess this faculty, which is similar to that which Hecatê is thought to possess among the Greeks, for Anubis is a deity of the lower world as well as a god of Olympus. Some are of the opinion that Anubis is Cronus. For this reason, inasmuch as he generates all things out of himself and conceives all things within himself, he has gained the appellation of “Dog.” There is, therefore, a certain mystery observed by those who revere Anubis; in ancient times the dog obtained the highest honours in Egypt; but, when Cambyses had slain the Apis and cast him forth, nothing came near the body or ate of it save only the dog; and thereby the dog lost his primacy and his place of honour above that of all the other animals. – 368e-f
