Pedro de los Ríos

Fray Pedro de los Ríos (died 1563–1565 ) was a Domician missionary in New Spain in the mid-16th century. Little is known about him, but he contributed to the creation of the manuscripts now known as the Codex Telleriano-Remensis and Codex Vaticanus A, which describe Aztec culture and history. The Codex Vaticanus A is also known as the Codex Ríos, after Pedro de los Ríos.
