An example of Tomaso Porcacchi’s plan of the Aztec capital of Temistitan. This is one of the earliest obtainable plans of the city and one of only a handful published in the sixteenth century. It includes a compass rose upper left. The map is printed by Simone Galignani and engraved by Girolamo Porro. The atlas is classed as an ‘Isolario’ a term used to define an atlas of largely island maps. The tradition of the ‘Isolario’ began in the Mediterranean Sea and the first printed one appeared at the hands of Bartolommeo dalli Sonetti in c.1485. This was followed by the notable works of Benedetto Bordone in 1528 and Porcacchi. Phillips (1909-) 167; Sabin (1868) 64149; Shirley T.Por 1a no. 28.
