In June 1767 British navigator Samuel Wallis made the first European contact with Tahiti. Wallis returned from his voyage in time to help the Royal Society decide that it would be an ideal location to observe the Transit of Venus. A big advantage was that Tahiti was one of the few islands in the South Pacific that they knew the longitude and latitude of. The Admiralty was not really interested in particularly where in the South Pacific the observation of the Venus transit would take place. They were more interested in the "secret" mission that would be revealed after the Venus transit observation: the search for the alleged southern continent. HM Bark Endeavour was chosen to take the astronomers and other scientists to Tahiti. James Cook was commissioned as Lieutenant and appointed to command the vessel. Cook was the obvious choice as he was an outstanding seaman with navigational qualifications, a capable astronomer and had observed a 1766 annular eclipse in Newfoundland that was communicated to the Royal Society by John Bevis.
