Portolani During this Period   The Pisana School The Pisana is the earliest example (1250-1296) of a portolano. It is the oldest Western navigation map, and as an extremely early (and well known) map which influenced all subsequent maps, especially those of the Catalana and Genovese schools. Although it may have been drawn up in Genoa, it is referred to as the Pisana map because it belonged to a well established family in Pisa during the 19th century. It depicts the Mediterranean Sea in correct proportions
