King Pelias sends his nephew Jason to fetch the Golden Fleece from Colchis, at the far end of the Black Sea, hoping he will never come back. Jason builds the Argo, gathers the greatest heroes of his day, Heracles among them, and sails east. Apollonius of Rhodes told the voyage in his Argonautica in the 3rd century BC, and he filled it with real coasts, harbours and local legends.
This route follows the outward voyage to Colchis. The way home is left out: ancient writers sent the Argo back by wildly different routes, up rivers into the Adriatic and even across Libya. The heroes and the fleece are myth; the shores, islands and ancient cities are real. Quotations are from R. C. Seaton's 1912 translation.
After ten years at Troy, Odysseus sets sail for his island home of Ithaca and takes another ten to get there: blown off course, he meets a man-eating Cyclops, a witch who turns his crew into pigs, the Sirens, Scylla and Charybdis and a nymph who will not let him go, losing every ship and every companion on the way. Homer's Odyssey, composed around the late 8th century BC, has been read as a map for as long as it has been read.
Already in antiquity the poem's places were linked to real coasts, mostly around Sicily and southern Italy. Those identifications are traditions, not facts, and the ancient geographer Eratosthenes doubted them all — so most pins here are marked speculative.
