Baltasar Jaime Martínez Compañón

Baltasar Jaime Martínez Compañón (1737–1797) was a Spanish prelate who served as Bishop of Trujillo, Peru, Peru from 1779 to 1790, at Trujillo Cathedral, and Archbishop of Bogotá, New Granada, from 1790 to 1797. He was responsible for founding new towns, building schools, and reforming the silver mine at Hualgayoc. He is most remarkable for his efforts to educate Trujillo's Indians and for his research into local plants, animals, archaeological ruins, music, and native cultures.

Background and education
Martínez Compañón was born in Cabredo, Navarre (Spain) and studied Religious Law at the Universities of Huesca and Zaragosa in Aragón before earning his bachelor's degree at the University of Oñate in Guipuzcoa in 1759, and his doctorate at Oñate in 1763. He was ordained as a Catholic priest in 1761. In 1766, he served as an advisor to the Holy Office of the Inquisition in Madrid.

Early career in America
In 1767, King Charles III of Spain named Martínez Compañón choirmaster of the Metropolitan Cathedral of Lima, Peru. In 1772 and 1773, he served as Secretary to the Sixth Provincial Church Council of Peru, held in Lima. From 1770 to 1778, he served as rector of the Saint Toribio seminary, also in Lima.

Bishop of Trujillo
King Charles III named Martínez Compañón Bishop of Trujillo, Peru, on February 25, 1778. While there, he explored his bishopric in a visitation that lasted two years, eight months, and eight days. During this time he gathered the information that would become the basis of his projects to found new towns and schools. He planned to create special schools for Indian boys and girls where they would learn trade and craft skills as well as basic literacy. He also imagined an elaborate plan to create a utopian mining town at the Hualgayoc silver mine, outside Cajamarca.

Archbishop of Bogotá
After arriving in Bogotá on March 12, 1791, Martínez Compañón repaired local churches, founded five primary schools throughout the city, and established a seminary. He also became friends with noted botanist José Celestino Mutis.

Death
Martínez Compañón died of old age on August 17, 1797. Local legend holds that a smell of flowers emanated from his corpse and for three days the sun did not shine.

Legacy
When Martínez Compañón died, he left behind a natural history collection of animals, plants, artifacts and manufactures. These comprised a total of 24 boxes. Today part of the collection is held at the Museo de América in Madrid, although the majority of it has been lost. He also sent to Spain a nine volume set of watercolor images depicting the people, plants, and animals of Trujillo, the Codex Martínez Compañón. Drawn by local artisans, these 1,372 images are a unique example of vernacular natural history produced in the colonial context. The originals survive today in the library of the Royal Palace in Madrid.
