"There are but 155 years left...at which time...the world will come to an end," wrote Christopher Columbus in his book Libro de Las Profecias, composed in 1502 between his 3rd and 4th voyages. "The sign which convinces me that our Lord is hastening the end of the world is the preaching of the Gospel recently in so many lands." Though his predictions were off, Columbus revealed his motivation for setting sail on his first voyage AUGUST 3, 1492, with the Nina, Pinta and the Santa Maria: "I spent seven years in your royal Court arguing the case with so many persons of such authority and learned in all the arts, and in the end they concluded that all was idle nonsense...yet the outcome will be the fulfillment of what our Redeemer Jesus Christ said...that..all that was written by him and by the prophets to be fulfilled." Columbus continued: "The Holy Scriptures testify...that this world will come to an end...St. Augustine says that the end of this world will occur in the seventh millennium following the Creation." Columbus ended: "I have already said that for the execution of the enterprise of the Indies, neither reason, nor mathematics, nor world maps were profitable to me; rather the prophecy of Isaiah was fulfilled."
