Unlikely since Columbus and the leaders of his expedition were committed to Christianity. Columbus believed he was specially chosen by God to bring the Gospel to the East.
Columbus’ Book of Prophecies is a study of the prophets of the Old Testament and the teaching of Christ about the duty to proclaim the Gospel to all nations. Columbus was a devout Catholic who attended Mass and received Holy Communion regularly. Columbus was a Third Order Franciscan who believed that the world should be converted to Christ.
Columbus’ journal in 1492, day after day, refers to Jesus and the need for divine help.
