Compare Sayce with the following "Notes on the Moses Myth," from Christianity and Mythology, by J. M. Robertson:

NOTES ON THE MOSES MYTH.

     I have been challenged for saying that the story of Moses and
     the floating basket is a variant of the myth of Horos and the
     floating island (Herod ii. 156).  But this seems sufficiently
     proved by the fact that in the reign of Rameses II., according
     to the monuments, there was a place in Middle Egypt which
     bore the name I-en-Moshe, "the island of Moses."  That is the
     primary meaning.  Brugsch, who proclaims the fact (Egypt
     Under the Pharaohs, ii. 117), suggests that it can also mean "the
     river bank of Moses."  It is very obvious, however, that the
     Egyptians would not have named a place by a real incident in
     the life of a successful enemy, as Moses is represented in Exodus.
     Name and story are alike mythological and pre-Hebraic, though
     possibly Semitic.  The Assyrian myth of Sargon, which is,
     indeed, very close to the Hebrew, may be the oldest form of all;
     but the very fact that the Hebrews located their story in Egypt
     shows that they knew it to have a home there in some fashion.
     The name Moses, whether it mean "the water-child" (so Deutsch)
     or "the hero" (Sayce, Hib. Lect. p. 46), was in all likelihood
     an epithet of Horos.  The basket, in the latter form, was
     doubtless an adaptation from the ritual of the basket-born
     God-Child, as was the birth story of Jesus.  In Diodorus Siculus
     (i. 25) the myth runs that Isis found Horos dead "on the water,"
     and brought
