Once you have passed them all, moored your ships on the far shore and set up altars on the beach to perform your vows, then cloak yourselves in purple, 480 veil your heads, so while the hallowed fires are burning in honor of the gods, no enemy presence can break in and disrupt the omens. Your comrades, you yourself must hold fast to this sacred rite, this custom. Your sons’ sons must keep it pure forever.
