Final answer:
Prince Henry the Navigator's interest in navigation was likely influenced by the prospects of wealth, his involvement in the Conquest of Ceuta, and his desire to extend Christianity and trade. The spirit of the age, including tales of glory and gold, also contributed to his enthusiasm for exploration.
Step-by-step explanation:
Origins of Henry the Navigator's Interest in Navigation
Portugal's Prince Henry the Navigator was instrumental in the Age of Exploration, particularly in spearheading Portuguese exploration of Africa and the Atlantic during the 1400s. His fascination with navigation and exploration seems to have been sparked by a combination of factors. One of the most significant influences on Prince Henry's curiosity would have been the potential for wealth from the untapped resources of Africa, as seen through his involvement in the conquest of Ceuta. In addition, his desire to extend Christianity and trade were also driving forces behind his motivation to explore. Although not directly mentioned in the text, the spirit of the age was filled with the glory of discovery and the potential for finding gold, which were common motives for exploration during this period. Thus, it is reasonable to infer that Prince Henry's interest in navigation was most closely aligned with the tales of sailors and explorers and his strategic ambitions for Portugal.
