Friar Pedro de Aguado (1513 or 1538 – late 16th or early 17th century) was a Spanish Franciscan friar who spent around 15 years in the New Kingdom of Granada, preaching to the indigenous people. During this time he published a work written by Fray Antonio de Medrano on the history of the region and Medrano's manuscript, Recopilación historial, which was almost ready for publication, between 1576 and 1583 but was unable to publish. The manuscript was used by other historians, but was not published until the twentieth century.[1]
