In 1893 Fridtjof Nansen froze a purpose-built ship into the Arctic ice on purpose. His bet was that the pack would carry it across the top of the world, and the sceptics called it self-destruction.
This route follows the voyage from Vardø to the pack ice, the drift, the sledge dash to 86°14′N, a hard winter in a stone hut and a lucky meeting at Cape Flora, ending at the museum where the ship rests. Ocean and ice stops have no map pin.
In 1725 a Russian naval captain set out across a continent to answer one question: are Asia and America joined? Vitus Bering's two Kamchatka expeditions, the second of them part of the Great Northern Expedition, took years of hardship to answer it.
The route follows seven places from the Tsar's order in Saint Petersburg to Bering's death on an uninhabited island in 1741. The stops are not one continuous line, so they are shown as separate markers. Dates are Old Style (Julian), as Russian records of the time kept them; the modern calendar runs 11 days ahead.
Between 1405 and 1433 the Ming court sent a fleet from Nanjing across the South China Sea and the Indian Ocean, seven times, under the admiral Zheng He. It came home with ambassadors and exotic animals.
This route follows the sequence from the shipyard in Nanjing through Java, Malacca, Ceylon, Calicut and Hormuz to Malindi in East Africa, and ends at his empty tomb. Most ports are approximate pins, and later temple traditions are marked as such.
On 26 August 1768 the Endeavour left Plymouth with 94 people aboard, bound for Tahiti to watch Venus cross the Sun. Almost three years later she anchored off the Kent coast again, having reached New Zealand and the east coast of Australia, and with many of her people lost to disease on the way home.
The route follows James Cook's own journal and modern accounts through ten stops, from the anchorage at Plymouth to the Great Barrier Reef and Batavia. Dates follow modern accounts, which sometimes differ by a day from the journal.
In the spring of 334 BC Alexander, the 22-year-old king of Macedon, crossed into Asia with an army of Macedonians and Greeks to make war on the Persian Empire. Eleven years later he had defeated the Persian king Darius III three times, taken Egypt, burned Persepolis and led his men to the rivers of the Punjab — and then died in Babylon at the age of 32, his empire stretching from Greece to India.
The route follows the campaign through its turning points, with Arrian's Anabasis, written four centuries later from earlier accounts, as the main guide. Several battlefields can only be placed approximately; their pins are marked as such.
