The Prince Henry may be taken as a symbol of wishes and efforts of anonymous navigators, cartographers, of cosmographers, merchants and adventurers who helped modern man to build new dimensions to the perspective of the world. A prince of remarkable qualities that worked in favor of the Kingdom and of the Catholic religion, with projects, subject to successes and failures, stubborn in realizing their desires, and a man deeply marked by the conditions and conveniences of life of his time. It is to mention that the author was awarded with the prize Henriquino, in 1960, in Portugal.

This provocative work challenges traditional accounts of Meriwether Lewis and William Clark’s expedition across the continent and back again. Uncovering deeper meanings in the explorers’ journals and lives, Exploring Lewis and Clark exposes their self-perceptions and deceptions, and how they interacted with those who traveled with them, the people they discovered along the way, the animals they hunted, and the land they walked across. The book discovers new heroes and brings old ones into historical focus. Thomas P. Slaughter interrogates the explorers’ dreams, how they wrote and what they aimed to possess, their interactions with animals, Indians, and each other, their sense of themselves as leaders and men, and why they feared that they had failed their nation and President. Slaughter’s Lewis and Clark are more confused, frightened, courageous, and flawed than in previous accounts. They are more human, their expedition more dramatic, and thus their story is more revealing about our own relationships to history and myth.
