Livio Sanuto (1520 – 1576) was a Venetian cartographer and scientific instrument maker produced, with his engraver brother, Giulio (fl. 1540-1588) – an array of some of the most important geographical works produced in Venice during the second half of the sixteenth century. These included a 27-inch globe and the 1588 12-sheet atlas, Geografia della Africa. Among Livio and Giulio's works were some, if not all of the maps prepared for Ruscelli's 1561 Ptolemy.
