 The name of the bay was used again to describe the river when the "Narration", his report of his expedition, was translated to Spanish and Italian, and definitively fixed by its use in the world map of cartographer Gerardus Mercator in 1569, according to historian Marcel Trudel.The name "Bas-Saint-Laurent", however, only appeared much later.In their "Histoire du Bas-Saint-Laurent", the historians Fortin and Lechasseur assert that the relation with the Saint Lawrence grew with the population of the region in the 19th century.
