The Basques were among the first people to catch whales commercially, as opposed to aboriginal whaling, and dominated the trade for five centuries, spreading to the far corners of the North Atlantic and even reaching the South Atlantic. The French explorer Samuel de Champlain, when writing about Basque whaling in Terranova (i.e. Newfoundland), described them as "the cleverest men at this fishing". By the early 17th century, other nations entered the trade in earnest, seeking the Basques as tutors, "for [they] were then the only people who understand whaling", lamented the English explorer Jonas Poole. Having learned the trade themselves, other nations adopted their techniques and soon dominated the burgeoning industry – often to the exclusion of their former instructors. Basque whaling peaked in the late 16th and early 17th centuries, but was in decline by the late 17th and early 18th centuries. By the 19th century, it was moribund as the right whale was nearly extinct and the bowhead whale was decimated. Bay of Biscay Beginnings There is a document, a bill, which states in the year 670 a delivery of 40 "moyos" (casks of 250 liters) of "aceite de ballena" (whale oil) or "grasa de ballena" (whale blubber) was made from Bayonne to the abbey of Jumièges, between Le Havre and Rouen, for its use in illumination. The authors that assessed this document suggest for such a request to be made by such a distant monastery that Basque whaling must have been well known – although the oil or blubber easily could have come from a stranded whale whose products were usurped by the church. Establishment and expansion Another author contends that the first mention of the use of whales by the Basques came in 1059, in which year a measure was passed to concentrate whale meat in the market of Bayonne. By the year 1150 whaling had spread to the Basque provinces in what is now Spain. In this year King Sancho the Wise of Navarre (r. 1150–94) granted San Sebastián certain privileges. The grant lists various goods that must be paid duties for warehousing, and among this list "boquinas-barbas de ballenas" or plates of whalebone (baleen) held a prominent place. By 1190, whaling had spread to Santander. In 1203, Alfonso VIII of Castile gave Hondarribia the same privileges that had been given to San Sebastian. In 1204, these privileges were extended to Mutriku and Getaria. Similar
