Sacrifice in the Iliad - Scene 1

They [the Achaians] threw over the anchor stones and made fast the stern cables
and themselves stepped out on to the break of the sea beach,
and led forth the hecatomb to the archer Apollo,
and Chryseis herself stepped forth from the sea-going vessel.
Odysseus of the many designs guided her to the altar
and left her in her father's arms and spoke a word to him:
'Chryses, I was sent here by the lord of men Agamemnon
to lead back your daughter and accomplish a sacred hecatomb
to Apollo on behalf of the Danaans, that we may propitiate
the lord who has heaped unhappiness and tears on the Argives.'

I.436-445

The Achaians beached their ships and unloaded the cattle, leading them to the altar.
