The School of Sagres. The construction of a historiographical myth.

Traditionally the school of Sagres is considered as an initiative of scientific research and training under the command of Henry the Navigator, which played a key role in his exploration and expansion project through the Atlantic Ocean. Until the 20th century, it has not been investigated under the lens of the professional historian, whom has unraveled the truth and has questioned its existence. The intention of this paper is to study the school in depth, establishing a historiographic trajectory from its origins until the present. The goal is to understand where historical reality begins, and the myth ends.
