So the heroes passed on their way till they came to the land of the Mariandyni, of whom one Lycus was king. Here his doom came upon Idmon, the seer, that he should perish; for though he was a prophet, yet his prophecy availed him not against fate. Now there chanced to be in the marsh a great boar, that lay wallowing in the mud. Great white tusks had he, and even the Nymphs feared him. And as Idmon walked by the river side, the boar rushed on him of a sudden out of the reeds, and smote him on the thigh with his tusk, making a great wound. The hero fell not, indeed, but shouted aloud; and his companions ran thither at his voice. And first Peleus cast his javelin at the beast, but missed his aim; and afterwards Idas smote him, and he gnashed his teeth upon the spear. Then the heroes carried back their companion to the ship, but he died even as they carried him. Then they abode in that place for three days, and on the fourth they made a great funeral for him; and Lycus and his people came also to do honor to the dead man. But while they mourned for him it befell that Tiphys, the pilot, died also; for he could not endure his great sorrow for his companion. So they buried Tiphys also; and for each they built a great tomb, to be a memorial to them who should come after. Sore dismayed were the heroes that their helmsman was dead, and they sat a long time in silence, and neither ate nor drank. Then Heré put courage into the heart of Ancæus, and he spake to Peleus, saying, “Is it well, son of Æacus, to abide here in the land of strangers? Here am I that know more of seamanship than of war, and others also as skilful; nor should we suffer loss if we set one of them at the helm.” Then spake Peleus in the midst of the heroes, “Why waste we time in sorrow, my friends? There are skilful helmsmen; many are in this company, of whom let us choose us out the best.” But Jason answered, “If there be such, why sit they here with the rest lamenting? I fear me much that we shall neither see the city of Æætes nor yet the land of Greece.” But Ancæus stood forth, saying that he would be their helmsman; so also did Euphemus and other two; but the heroes chose Ancæus.
