"In doubt, we bade Eurypylus explore / Apollo's oracle, and back he brought / the dismal news: With blood, a maiden's gore, / ye stilled the winds, when Trojan shores ye sought. / With blood again must your return be bought; / an Argive victim doth the God demand."

Then Dymas brave / and Hypanis by comrades' hands are slain. / Nor, Panthus, thee thy piety can save, / nor e'en Apollo's wreath preserve thee from the grave.

Hither we sail and on this island fair, / worn out, find welcome in a sheltered bay, / and, landing, hail Apollo's town with prayer.
