Aeson, son of Cretheus, had a son Jason by Polymede, daughter of Autolycus. Now Jason dwelt in Iolcus, of which Pelias was king after Cretheus.1 But when Pelias consulted the oracle concerning the kingdom, the god warned him to beware of the man with a single sandal. At first the king understood not the oracle, but afterwards he apprehended it. For when he was offering a sacrifice at the sea to Poseidon, he sent for Jason, among many others, to participate in it. Now Jason loved husbandry and therefore abode in the country, but he hastened to the sacrifice, and in crossing the river Anaurus he lost a sandal in the stream and landed with only one. When Pelias saw him, he bethought him of the oracle, and going up to Jason asked him what, supposing he had the power, he would do if he had received an oracle that he should be murdered by one of the citizens. Jason answered, whether at haphazard or instigated by the angry Hera in order that Medea should prove a curse to Pelias, who did not honor Hera, “ I would command him,” said he, “ to bring the Golden Fleece. ” No sooner did Pelias hear that than he bade him go in quest of the fleece. Now it was at Colchis in a grove of Ares, hanging on an oak and guarded by a sleepless dragon.2
Sent to fetch the fleece, Jason called in the help of Argus, son of Phrixus; and Argus, by Athena's advice, built a ship of fifty oars named Argo after its builder; and at the prow Athena fitted in a speaking timber from the oak of Dodona.3 When the ship was built, and he inquired of the oracle, the god gave him leave to assemble the nobles of Greece and sail away. And those who assembled were as follows:4 Tiphys, son of Hagnias, who steered the ship; Orpheus, son of Oeagrus; Zetes and Calais, sons of Boreas; Castor and Pollux, sons of Zeus; Telamon and Peleus, sons of Aeacus; Hercules, son of Zeus; Theseus, son of Aegeus; Idas and Lynceus, sons of Aphareus; Amphiaraus, son of Oicles; Caeneus, son of Coronus; Palaemon, son of Hephaestus or of Aetolus; Cepheus, son of Aleus; Laertes son of Arcisius; Autolycus, son of Hermes; Atalanta, daughter of Schoeneus; Menoetius, son of Actor; Actor, son of Hippasus; Admetus, son of Pheres; Acastus, son of Pelias; Eurytus, son of Hermes; Meleager, son of Oeneus; Ancaeus, son of Lycurgus; Euphemus, son of Poseidon; Poeas, son of Thaumacus; Butes, son of Teleon; Phanus and Staphylus, sons of Dionysus; Erginus, son of Poseidon; Periclymenus, son of Neleus; Augeas, son of the Sun; Iphiclus, son of Thestius; Argus, son of Phrixus; Euryalus, son of Mecisteus; Peneleos, son of Hippalmus; Leitus, son of Alector; Iphitus, son of Naubolus; Ascalaphus and Ialmenus, sons of Ares; Asterius, son of Cometes; Polyphemus, son of Elatus.
