Typhon As Set

Thus they showed that all those whose statues stood there had been good men, but quite unlike gods. Before these men, they said, the rulers of Egypt were gods, but none had been contemporary with the human priests. Of these gods one or another had in succession been supreme; the last of them to rule the country was Osiris' son Horus, whom the Greeks call Apollo; he deposed Typhon, and was the last divine king of Egypt. Osiris is, in the Greek language, Dionysus.


- Herodotus, The Histories, Book 2, Chapter 144


(Here, Herodotus is explaining a story from Egyptian myth by bringing up the Greek gods that were used as parallels. He explicitly points out that Apollo was used as a stand-in for Horus, and that Dionysus was used as a stand-in for Dionysus, but replaces Set's name with Typhon's without explicitly explaining that. He substitutes Set with Typhon elsewhere in this source.)
