From the Suda:
“A person is a person’s god.” This proverb is for when people are unexpectedly saved by human being and become famous because of this. There are also the proverbs “A person [like] Euripos”; “Chance [like] Euripos”, “An opinion [like the] Euripos”—these proverbs are for people who change easily and are not stable.”
Ἄνθρωπος ἀνθρώπου δαιμόνιον: παροιμία ἐπὶ τῶν ἀπροσδοκήτως ὑπὸ ἀνθρώπου σῳζομένων καὶ δι’ αὐτῶν εὐδοκιμούντων. καὶ Ἄνθρωπος Εὔριπος, Τύχη Εὔριπος, Διάνοια Εὔριπος. ἐπὶ τῶν ῥᾷστα μεταβαλλομένων καὶ ἀσταθμήτων ἀνθρώπων.
Explained elsewhere:
“Euripos: A sea strait, or a water body between two [bodies] of land. This one is between Boiôtia and Attica. The water there changes direction seven times a day.”
Εὔριπος: πέλαγος στενόν, ἢ τόπος ὑδατώδης μεταξὺ δύο γαιῶν. τουτέστι Βοιωτίας καὶ ᾿Αττικῆς. ἑπτάκις δὲ τῆς ἡμέρας τὸ ἐκεῖσε ὕδωρ τρέπεται.
