That would be completely false. There's a 20 page chapter on Anup and a chapter on Typhon who is also "Set" (or the Christian version of Satan) in Christ in Egypt:
"...the Roman Empire by the time Christianity was created. With this famed goddess Isis came her entourage, including one of her most faithful attendants, the mysterious god Anubis, also called “Anup” or “Anpu.” The popularity of Isis and her associates, including Anubis, is highlighted by Dr. Frank Cole Babbitt (1867-1935), a professor of Greek language and literature at Trinity College, and a translator of Plutarch’s Moralia:
"That the worship of Isis had been introduced into Greece before 330 B.C. is certain from an inscription found in…Peiraeus…in which the merchants from Citium ask permission to found a shrine of Aphrodite on the same terms as those on which the Egyptians had founded a shrine of Isis. In Delos there was a shrine of the Egyptian gods, and in Plutarch’s own town they must have been honoured, for there have been found two dedications to Serapis, Isis, and Anubis, as well as numerous inscriptions recording the manumission of slaves, which in Greece was commonly accomplished by dedicating them to a god, who, in these inscriptions, is Serapis (Sarapis)…."

“The god Seth, called Typhon by the Greek writers, was the Satan of later Egyptian mythology. He was the personification of the evil in the world, just as Osiris was the personification of the good.”
