Plutarch, De Iside et Osiride 31

Αἰγύπτιοι δὲ πυρρόχρουν γεγονέναι τὸν Τυφῶνα νομίζοντες καὶ τῶν βοῶν τοὺς πυρροὺς καθιερεύουσιν, οὕτως ἀκριβῆ ποιούμενοι τὴν παρατήρησιν, ὥστε, κἂν μίαν ἔχῃ τρίχα μέλαιναν ἢ λευκήν, ἄθυτον ἡγεῖσθαι. θύσιμον γὰρ οὐ φίλον εἶναι θεοῖς, ἀλλὰ τοὐναντίον, ὅσα ψυχὰς ἀνοσίων ἀνθρώπων καὶ ἀδίκων εἰς ἕτερα μεταμορφουμένων σώματα συνείληφε. διὸ τῇ μὲν κεφαλῇ τοῦ ἱερείου καταρασάμενοι καὶ ἀποκόψαντες εἰς τὸν ποταμὸν ἐρρίπτουν πάλαι, νῦν δὲ τοῖς ξένοις ἀποδίδονται. τὸν δὲ μέλλοντα θύεσθαι βοῦν οἱ σφραγισταὶ λεγόμενοι τῶν ἱερέων κατεσημαίνοντο, τῆς σφραγῖδος, ὡς ἱστορεῖ Κάστωρ, γλυφὴν μὲν ἐχούσης ἄνθρωπον εἰς γόνυ καθεικότα ταῖς χερσὶν ὀπίσω περιηγμέναις, ἔχοντα κατὰ τῆς σφαγῆς ξίφος ἐγκείμενον· ἀπολαύειν δὲ καὶ τὸν ὄνον, ὥσπερ εἴρηται, τῆς ὁμοιότητος διὰ τὴν ἀμαθίαν καὶ τὴν ὕβριν οὐχ ἧττον ἢ διὰ τὴν χρόαν οἴονται. διὸ καὶ τῶν Περσικῶν βασιλέων ἐχθραίνοντες μάλιστα τὸν Ὦχον ὡς ἐναγῆ καὶ μιαρόν, ὄνον ἐπωνόμασαν. κἀκεῖνος εἰπών ὁ μέντοι ὄνος οὗτος ὑμῶν κατευωχήσεται τὸν βοῦν, ἔθυσε τὸν Ἆπιν, ὡς Δείνων ἱστόρηκεν. οἱ δὲ λέγοντες ἐκ τῆς μάχης ἐπʼ ὄνου τῷ Τυφῶνι τὴν φυγὴν ἑπτὰ ἡμέρας γενέσθαι, καὶ σωθέντα γεννῆσαι παῖδας Ἱεροσόλυμον καὶ Ἰουδαῖον, αὐτόθεν εἰσὶ κατάδηλοι τὰ Ἰουδαϊκὰ παρέλκοντες εἰς τὸν μῦθον.

The Egyptians, because of their belief that Typhon was of a red complexion, also dedicate to sacrifice such of their neat cattle as are of a red colour, but they conduct the examination of these so scrupulously that, if an animal has but one hair black or white, they think it wrong to sacrifice it; for they regard as suitable for sacrifice not what is dear to the gods but the reverse, namely, such animals as have incarnate in them souls of unholy and unrighteous men who have been transformed into other bodies. For this reason they invoke curses on the head of the victim and cut it off, and in earlier times they used to throw it into the river, but now they sell it to aliens. Upon the neat animal intended for sacrifice those of the priests who were called Sealers used to put a mark; and their seal, as Castor records, bore an engraving of a man with his knee on the ground and his hands tied behind his back, and with a sword at his throat. They think, as has been said, that the ass reaps the consequences of his resemblance because of his stupidity and his lascivious behaviour no less than because of his colour. This is also the reason why, since they hated Ochus most of all the Persian kings because he was a detested and abominable ruler, they nicknamed him the Ass; and he remarked, But this Ass will feast upon your Bull, and slaughtered Apis, as Deinon has recorded. But those who relate that Typhon’s flight from the battle was made on the back of an ass and lasted for seven days, and that after he had made his escape, he became the father of sons, Hierosolymus and Judaeus, …
