Description

  • This Spanish map of the Río Uruguay from Estancia San Gregorio to Yapeyu was prepared by Joseph Varela y Ulloa (1739-94), the commander of the Spanish party of the joint Spanish-Portuguese boundary commission that surveyed the Uruguay and Paraguay river basins between 1784 and 1788. The survey took place after the signing, in October 1777, of the First Treaty of San Ildefonso between Spain and Portugal, which settled the outstanding border disputes between the two empires in the region of the Rio de la Plata. The map shows the route of a survey party and the river and intersecting streams, with pictorial representations of rapids and settlements.
