Engraving by Whymper of the Leeambye or Zambesi River, 'called by the Natives Musyoatunya (Smoke-Sounding)'. In 1855, Scottish missionary Dr David Livingstone (1813-1873) first saw the Victoria Falls, now in Zimbabwe, while searching for a route to the African interior. Livingstone named the falls after Queen Victoria (1819-1901). One of the Seven Wonders of the World, it is the largest curtain of falling water on Earth. Illustration from Livingstone's 'Missionary travels and researches in South Africa', published in London in 1857.
