Mrs Dalloway unfolds in one June day across Westminster, St James's Park, Piccadilly's Hatchards bookshop and Regent's Park. Big Ben marks the hours for Clarissa, preparing her party, and for Septimus, a war veteran; the two never meet.
This route follows the characters through the London they walk, almost all of it still standing. The Dalloways' house, the florist and the doctors are fictional.
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.
