The French explorer Jacques Cartier sailed along its shore in the summer of 1534. He provided its first written description and named it "Isle de l'Assomption", because he reached it on the Day of the Assumption of Mary. This name had fallen into disuse by 1656. About 1586, the historian André Thevet wrote that "the savages named Naticousti", while Samuel de Champlain spelled it Antiscoti (1612), Antiscoty (1613), Enticosty (1625) and Antycosty (1632). From that time on, France had officially incorporated the island into its colonial empire.
