The Pinzon brothers supplied Columbus Atlantic route intelligence from Papal archives

Evidence

Martin, after a business trip to Rome, which included a visit to the Papal Court in 1491, had returned to Palos with detailed information on an Atlantic route that he had gathered from the Papal library. He shared this material with Columbus and helped to arrange with Pinelli and Santangel for a police fine against Palos to be redirected for support of Columbus’s project. Martin and Vincente sailed with Columbus as captains of the Pinta and Nina. — Cedric J. Robinson, Black Marxism_ The Making of the Black…, 1835

• QUESTION: The claim that Martin Pinzon gathered Atlantic navigational intelligence from the Vatican library and fed it to Columbus is obscure; worth chasing its sourcing and the role of Church cartographic knowledge in funding the voyage.
