Pedro de los Ríos
Pedro de los Ríos was a Domician missionary in Mexico 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.
