JUSTINIAN0, Bartolome (hoos-teen-yah'-no), Spanish explorer, died in Asuncion, Paraguay, late in the 16th century. He went to Rio de la Plata as treasurer of the expedition of Juan de Salazar de Espinosa in 1552, but was shipwrecked near the coast of Brazil. There was now a division between the captains Juan de Salazar and Hernando de Frejo, and the friends of the former remained with him in the place that afterward was known as San Vicente. There they passed two years, and at the end of this time Captain Salazar sent Justiniano, as the most capable man among them, to ask assistance from Domingo de Irala, who sent Captain Nuflo de Chavez to their rescue, in 1555. On reaching Asuncion, Justiniano gave to Irala the stores and ammunition which he brought with him for the government of the country. In executing the orders of the king, they met with much opposition by the settlers, many of whom wrote letters to the court against Irala and treasurer Justiniano. Justiniano seems to have been exonerated, and settled at Asuncion, acting with ability in the wars against the natives. After he served for several years, he resigned his post of treasurer.
