The Iliad 21.184–199
to strive with the children of the mighty son of Cronos, albeit for one begotten of a River. Thou verily declarest that thy birth is from the wide-flowing River, whereas I avow me to be of the lineage of great Zeus. The father that begat me is one that is lord among the many Myrmidons, even Peleus, son of Aeacus; and Aeacus was begotten of Zeus. Wherefore as Zeus is mightier than rivers that murmur seaward, so mightier too is the seed of Zeus than the seed of a river. For lo, hard beside thee is a great River, if so be he can avail thee aught; but it may not be that one should fight with Zeus the son of Cronos. With him doth not even king Achelous vie, nor the great might of deep-flowing Ocean, from whom all rivers flow and every sea, and all the springs and deep wells; howbeit even he hath fear of the lightning of great Zeus, and his dread thunder, whenso it crasheth from heaven.
κεῖσʼ οὕτως· χαλεπόν τοι ἐρισθενέος Κρονίωνος
παισὶν ἐριζέμεναι ποταμοῖό περ ἐκγεγαῶτι.
φῆσθα σὺ μὲν ποταμοῦ γένος ἔμμεναι εὐρὺ ῥέοντος,
αὐτὰρ ἐγὼ γενεὴν μεγάλου Διὸς εὔχομαι εἶναι.
τίκτέ μʼ ἀνὴρ πολλοῖσιν ἀνάσσων Μυρμιδόνεσσι
Πηλεὺς Αἰακίδης· ὃ δʼ ἄρʼ Αἰακὸς ἐκ Διὸς ἦεν.
τὼ κρείσσων μὲν Ζεὺς ποταμῶν ἁλιμυρηέντων,
κρείσσων αὖτε Διὸς γενεὴ ποταμοῖο τέτυκται.
καὶ γὰρ σοὶ ποταμός γε πάρα μέγας, εἰ δύναταί τι
χραισμεῖν· ἀλλʼ οὐκ ἔστι Διὶ Κρονίωνι μάχεσθαι,
τῷ οὐδὲ κρείων Ἀχελώϊος ἰσοφαρίζει,
οὐδὲ βαθυρρείταο μέγα σθένος Ὠκεανοῖο,
ἐξ οὗ περ πάντες ποταμοὶ καὶ πᾶσα θάλασσα
καὶ πᾶσαι κρῆναι καὶ φρείατα μακρὰ νάουσιν·
ἀλλὰ καὶ ὃς δείδοικε Διὸς μεγάλοιο κεραυνὸν
δεινήν τε βροντήν, ὅτʼ ἀπʼ οὐρανόθεν σμαραγήσῃ.
