During his reign the Depot published a prodigious number of charts and maps, among which were large folio-format sea-charts of France, the Neptune Francois.
Bellin set a very high standard of workmanship and accuracy thus gaining for France a leading role in European cartography and geography.
He was one of the Encyclopédistes, a group of 18th century intellectuals in France who compiled the 35-volume Encyclopédie which was edited by Denis Diderot and Jean le Rond d'Alembert.
The Encyclopédistes, were part of the group called philosophes among whose members were the great minds of the Age of Enlightenment, e.g., Montesquieu, Voltaire, Rousseau, Baron d'Holbach.
Shown in Bellin's map was an island named "Limasava", a word invented in 1667 by Spanish friar, Fr.
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.
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.
Largely with the appearance of the eyewitness account of Ginés de Mafra, the only seaman in Magellan's fleet to return to Mazaua, whose testimony reveals a concrete, measurable description of Mazaua, the skein starting from the garbled version of Pigafetta by Ramusio to the mishandling by Combés to Bellin and finally to Amoretti has been unraveled: Pigafetta's Gatighan is Bellin's Limasava.
