José Arlegui (c. 1686-1750) was a Spanish Franciscan theologian of the 18th century, from Biscay, who wrote on theological subjects, some of them related to the ethnology of Mexico.
He was first attached to the Franciscan province of Cantabria, then transferred to Zacatecas in Mexico.
His most important work was the Cronica de Zacatecas, which was published in 1737. He gives an account of the missions in his province, including many reports on the native Americans of Zacatecas. This is a major primary source for them, who are otherwise hardly touched by contemporary published documents, and of the first attempts to convert them to Christianity. The work is divided into five parts, discussing:[1]
Ernest J. Burrus describes the chronicle as "very uneven", providing important sources on topics close to Arlegui's own time, but "inaccurate and untrustworthy" on earlier history. criticizes Arlegui's chronology as inaccurate and contradictory, while praising him for distinguishing himself among contemporary chroniclers by attempting to include it at all.
