Chryseis left the ship after it entered the harbour at Chryse, establishing her presence there.

“When they had come inside the harbour they furled the sails and laid them in the ship’s hold; they slackened the forestays, lowered the mast into its place, and rowed the ship to the place where they would have her lie; there they cast out their mooring-stones and made fast the hawsers. They then got out upon the sea-shore and landed the hecatomb for Apollo; Chryseis also left the ship”
