Cuban Folk-Lore by L. Roy Terwilliger

Fortunately for history, most early Spanish expeditions were accompanied by such observers as Las Casas, Cortés, Gomara and Oviedo, who although differing in minor details and unreliably eulogistic of their own expeditions and leaders have agreed on their accounts of the habits of the Indians as found at the time of the discovery.

Bartolomé Las Casas in particular made a study of the Indians and in so far as possible sought to relieve their sufferings.
