Christopher Columbus credited Juan Cabrero, along with Diego de Deza, as being responsible for the Catholic Monarchs' acceptance of his Indies Enterprise proposal in 1492.
Notes on verification
Multiple independent sources corroborate this claim, including direct references to Columbus's 1504 letters crediting both Juan Cabrero and Diego de Deza. The sources include a reputable historical collection (Raab Collection) and historical texts that cite primary documentation. The consistent mention across different sources of Columbus's own attribution strengthens confidence.
