When ten years old, however, Christopher was made to work in the wool shop and became his father's apprentice, with little free time from the loom to go about his own affairs. It is thought that he did not take kindly to this business and he may have run away, for a few years later we hear rumors of him in the University of Pavia, where, although a lad in his teens, he was greatly interested in the studies of geography and astronomy. He had already learned all that was then known about the science of navigation and the use of the few rude instruments with which mariners determined their position on the sea. He had also mastered the science of making maps and was so skilful at drawing them that he could earn his living by this means. He had taken his first trips as a sailor and visited many ports in the immediate vicinity of Genoa and perhaps he had gone even farther, for the love of adventure and of a wandering life were in his blood.
When a very young man the wanderings of Columbus brought him to Portugal, where he lived for a time, at Lisbon, with his brother Bartholomew, who already had made his home there and was drawing maps for a living. The Portuguese were the best sailors of Europe and the boldest explorers. Perhaps that was the reason why Columbus went to Portugal to live. But another story, later told by his son, says that he was attacked by pirates when in command of a vessel not far from the Portuguese coast, and saved his life by swimming to the shore.
While Columbus was drawing maps in Lisbon, he used to go to a church that was visited by a beautiful girl called the Lady Philippa, the cousin to no less a person than the Archbishop of Lisbon himself. Columbus fell in love with her and attended the church whenever he believed that it would be possible to see her there. She, in turn, began to look with kindness upon him and at last Columbus and the Lady Philippa were married and the marriage proved to be a very happy one.
Philippa's grandfather had himself been a bold sailor and an adventurous explorer and discovered the Madeira Islands, where his granddaughter owned some property. As she did not like the idea of having her husband work constantly making maps, the young couple went to live on the Madeira Islands at a place called Porto Santo, where Philippa's brother was Governor.
