Álvar Núñez Cabeza de Vaca (Spanish pronunciation: [ˈalβaɾ ˈnũɲeθ kaˈβeθa ðe ˈβaka]; c. 1488/1490/1492 – c. 1557/1558/1559/1560) was a Spanish explorer of the New World, and one of four survivors of the 1527 Narváez expedition. During eight years of traveling across what is now the US Southwest, he became a trader and faith healer to various Native American tribes before reconnecting with Spanish civilization in Mexico in 1536. After returning to Spain in 1537, he wrote an account, first published in 1542 as La relación y comentarios ("The Account and Commentaries"), which in later editions was retitled Naufragios y comentarios ("Shipwrecks and Commentaries"). Cabeza de Vaca is sometimes considered a proto-anthropologist for his detailed accounts of the many tribes of Native Americans t
