Final answer:
Without the full passage, Hindbad's motivation cannot be deduced. However, historic motivations for exploration have typically included seeking wealth, religious conversions, and national glory, as shown in the motivations of explorers such as Columbus and Zheng He, and the influence of travel literature like Marco Polo's Travels.
Step-by-step explanation:
The passage from The Seven Voyages of Sindbad the Sailor is not fully provided, so it is not possible to determine what Hindbad is most motivated by without the context of the given passage. However, in relation to the broader theme of exploration referenced in the supplementary material, explorers during the times of Sindbad, Columbus, and Zheng He often operated under a confluence of motivations including God, glory, and gold. These motivations drove the explorers to embark on perilous voyages in search of new lands, wealth, and opportunities for spreading their faith.
For instance, Portuguese and Spanish explorers were motivated by the desire to spread Christianity and counter the influence of Islam. Chinese explorer Zheng He was motivated by displaying the power of China and expanding its tribute system. Travel accounts, like Marco Polo's Travels, exercised a considerable influence on explorers including Columbus, whose aspirations were stoked by tales of fabulous monsters and rich, exotic lands.
