Bellin contributed a number of maps to 15-vol.
Histoire Générale des Voyages of
Antoine François Prévost or simply known l'Abbé Prevost. One of these maps led to a geographical blunder whose impact reverberates to this day. This was the map of the Philippines which Bellin copied from a world-famous chart produced in 1734 by the Spanish missionary to the Philippines,
Fr. Pedro Murillo Velarde. Unlike many other European mapmakers of the time who outright appropriated Murillo's map, Bellin had the intellectual integrity to fully credit Murillo as his source, an open acknowledgement shown in the title
cartouche of Bellin's map which came out the same year as the original work by Murillo. Shown in Bellin's map was an island named "
Limasava", a word invented in 1667 by Spanish friar,
Fr. Francisco Combés, S.J., to refer to the way station of the
Armada de Molucca under the command of the Portuguese captain-general
Fernao de Magalhaes during its navigation in
Philippine waters. Combés, who had not read a single eyewitness account of the
Magellan expedition relied on two sources, the hopelessly garbled Italian translation of the Antonio Pigafetta account by
Giovanni Battista Ramusio and the secondhand account by
Antonio de Herrera y Tordesillas. Ramusio wrote the fleet anchored in March–April 1521 in Butuan in Mindanao, and from there sailed for Cebu with a brief stopover at "
Messana". In the authentic Pigafetta account, the port was an isle named
Mazzaua while the stopover isle was named
Gatighan.
Antonio de Herrera y Tordesillas gave a faithful narration of the Mazzaua anchorage. Combés disregarded de Herrera's version and adopted Ramusio's. He wrote that Magellan's fleet had anchored at Butuan and from there sailed for Cebu making a stop at a way station he named
Limasaua. Five years earlier than Combés, Fr. Francisco Colín wrote the Armada moored at Butuan from March–April 1521 where Magellan and his men together with the natives celebrated an Easter Sunday mass on 31 March 1521. From Butuan the fleet sailed for Cebu making a brief stop at a way station he called "
Dimasaua", an invented word meaning "this is not the Mazagua of Antonio de Herrera where supposedly an Easter Sunday mass was held which I already said happened in Butuan." This episode was projected in the 1734 map made by Murillo who used Combés name, "Limassava" not "Dimasaua" which map Bellin copied. ==Gatighan becomes Limasava==
