Martin Frobisher’s voyage in search of the North West Passage

Martin Frobisher's map of his route across the North Atlantic to Greenland in 1576, with the straits he supposedly discovered there. However it is based on his belief in the existence of the mythical island of 'Frisland', causing him to mistake Greenland for his true location on Baffin Island in Canada. Frobisher (1535-94) intended to find the North West Passage: he landed on Greenland but thought it to be the non-existent Frisland shown on his charts. When he sailed on and touched land again he believed he had arrived in Greenland when in fact he was at what is now Frobisher Bay on Baffin Island in the Canadian Arctic. Entering the bay he believed he had discovered a strait on Greenland, and even two more voyages (1577 & 1578) did nothing to make him doubt himself. Over a century later this map still shows Frobisher's Strait on Greenland, although Frisland had been consigned to history.
