An 17th century map of Paraguay

A map of Paraguay, centred on the Parana River, with the Atlantic coast from São Paulo in Brazil south to the Rio de la Plata, and the Pacific coast of Chile from Arica south to Santiago, with Cusco. Buenos Ayres is marked, but the map predates the founding of Montevideo by over eighty years. Of interest is the river route from Postosi, the richest silver mine in history, to Buenos Ayres.
