An official world map by Diogo Ribeiro described "from west to east, the first island, 'Mascarenhas', the second, 'Santa Apolonia' and the third, 'Domingo Froiz.' "[2] The three islands (Réunion, Mauritius and Rodrigues) were encountered some years earlier by chance during an exploratory expedition of the coast of the Bay of Bengal led by Tristão da Cunha. The expedition ran into a cyclone and was forced to change course. Thus, the ship Cirne of the captain Diogo Fernandes Pereira, came into view of Réunion island on 9 February 1507.
