Cristobal De Acuna, a Spanish Jesuit missionary in Chili and Peru, born at Burgos in 1597. He was one of the early explorers of the Amazons, being attached to Texeira's expedition to that river (1639-41), with the special object of reporting the incidents of the exploration. Acuna returned to Spain with an interesting narrative of it, which he published at Madrid; but the distraction of the country prevented the government from taking any interest in the colonization of the region to which so much energy and talent had been devoted. He once more went to South America, and died on a journey from Panama to Lima.
