Antonio’s brother, Diego de León Pinelo, became a professor in the University of San Marcos and rector of that institution for the years 1656 and 1657. He was appointed Protector of the Indians, and later fiscal of the audiencia of Lima. His extensive knowledge of legal and ecclesiastical matters was generally recognized, and many of his writings on juridical subjects were made public. In 1660 the Council of the Indies sent Padilla’s letter to the viceroy, the letter treating of the grievances, frauds, and acts of injustice under which the Indians suffered. At the same time the king ordered that a commission should be formed to examine the evils referred to, and seek a remedy. In obedience to a request from the viceroy Diego de León Pinelo set forth the misfortunes and extortions imposed upon the Indians. Pinelo’s report and Padilla’s letter were printed at Lima. The amount of attention given to this subject by the viceregal government may be inferred from the fact that the decrees, complaints, and claims issued during Alva’s term as viceroy, between 1655 and 1661, filled, when written, twenty-five books with 9,660 leaves. The attention bestowed upon this subject gives some indication of the extent of the abuses and excesses perpetrated by the corregidores and parish priests.[195] [Sidenote: Juan de León Pinelo] The second brother of Antonio, Juan de León Pinelo, who, as already indicated, studied at the University of San Marcos, became a cura at Potosí, and later went to Spain with Antonio. He was subsequently transferred to Puebla de los Angeles, and became a canon in the Cathedral of that city. His writings, published and unpublished, deal chiefly with ecclesiastical questions.[196] [Sidenote: Corral Calvo de la Torre] Juan del Corral Calvo de la Torre, born in the town of La Plata, in Upper Peru, studied in Lima, and was granted the title of advocate by the audiencia. He became a member of the audiencia in Santiago in 1698, and while occupying this position prepared his extensive work, designed to be three volumes in folio, under the title of _Expositio ac explanatio omnium legum Recopilat Indiarum_. But his application for permission to publish it received from the king the following reply: [Sidenote: Royal refusal of manuscript]
