made got the name Catalan Atlas, and it is the most important Catalan map of the medieval period. The first two leaves, forming the oriental portion of the Catalan Atlas, illustrate numerous religious references as well as a synthesis of medieval mappae mundi (Jerusalem located close to the center) and the travel literature of the time, notably Marco Polo's Book of Marvels and the Travels, and Voyage of Sir John Mandeville. Many Indian and Chinese cities can be identified. The explanatory texts report customs described by Marco Polo. Cresques, who knew Arabic, also used the travel narratives of Moroccan explorer Ibn Battuta. Mecca has a blue dome and shows Muslim prayer. The text next to the image is: While the areas under Muslim control were marked with domes, Jerusalem was surrounded by tales from Old and New Testaments like the Garden of Eden, the crucifixion, Noah's Ark and others.

He was probably the father of Gabriel de Vallseca, author of yet another famous mapamundi, one later used by Amerigo Vespucci. Gabriel also produced a very accurate maps of Black Sea and Mediterranean Sea. Another Jewish cartographer was Mecia de Vildestes. An outstanding map by Vildestes dated 1413 is proudly featured at the Bibliothèque Nationale of Paris. Anti-Jewish persecutions brought the end to the famous
