Fagles translation

Suddenly down from the mountains' rocky crags
Poseidon stormed with giant, lightning strides and
the looming peaks and tall timber quaked
Beneath his immortal feet as the sea lord surged on.

αἶψα δ᾽ ἀπ᾽ οὐρεσίφων σκοπέλων κατέβη Ποσειδάων, βῆ δὲ μέγ᾽ ἀΐσσων· τρέμε δ᾽ οὔρεα μακρὰ καὶ ὕλη ἀθανάτοισιν ὑπὸ ποσὶ κυανοχαίτης ἄνακτος, ἐσσυμένου πόντοιο κατὰ κλύδωνα θαλάσσης
