Antonio Salamenca 

In the mid sixteenth century, the twin Italian centres of Venice and ROME came to dominate European map-publishing. 

The most important figure in Venice was Giacomo Gastaldi and in Rome the print seller and publisher Antonio Lafreri. 

The 1540s saw an increasing number of new maps being published replacing the Ptolemy corpus, but many of these today are known through the derivatives of them being published in Rome.  

This superbly double-cordiform world map is a close copy of a 1538 map by Gerard Mercator.
