The earliest document (a bill) that mentions the whale oil or blubber dates from 670. In 1059, Labourdin whalers already gave to the viscount the oil of the first captured animal. It seems that Basques disliked the taste of whales but made good business selling their meat and oil to the French, Castilian and Flemish. Basque whalers used for this activity the longboats known as traineras, that only allowed whaling near the coast or based in a larger ship.
