Girolamo Porro (1520 - 1604¬) was an Venetian engraver, humanist, illustrator, map maker, and publisher. Porro was born in Padua but lived most of his life in Venice. Porro worked with a number of important Venetian humanists including Camillo Camilli, Scipione Barbuo, Porcacchi, Ruscelli, and Ariosto. Cartographically Porro has produced only a few works, but these include such important works as the maps for Porcacchi's 1572 Isole piu Famose del Mondo (including the first obtainable specific map of North America), and the maps included with Ruscelli's 1574 Italian translation of Ptolemy's Geographia.
