Hernando de Talavera's commission examines Columbus's proposal in Castile

From about 1486 a commission headed by Hernando de Talavera, confessor to Queen Isabella, considers Columbus's plan. It meets only now and then and advises against it in 1490 (some sources say 1491); the monarchs overrule it in 1492.
