CHAPTER X.
CAPE BOJADOR AND THE AZORES.

In 1428, Don Pedro, Henry's elder brother, had come home from his travels, with all the books and charts he had collected to help the explorers—and it is practically certain that the Mappa Mundi given him in Venice acted as a direct suggestion to the next attempts on west and south—westward to the Azores, southward towards Guinea.
