Lunar eclipse observations taken during Captain Cook's second Pacific voyage, from 'Complete History of Captain Cook's First, Second and Third Voyages' (1784). Captain James Cook (1728-1779), the famed navigator and hydrographer, transformed the West's knowledge of the Pacific region after making three exploratory voyages there and circumnavigating the globe twice. During this second voyage (1772-1775), in the ships 'Adventure' and 'Resolution', Cook and his crew crosed the latitude 70 degrees, the furthest south then reached by Europeans, and visited Easter Island.
