In the 16th century there were published in Italy many so-called Island descriptions. One of those was L'Isole piu famose del Mondo by Thomaso Porcacchi. The book contains a map of Iceland made by Girolamo Porro. The map, printed after an engraving, is well done. Porro, has like many others cartographers, sought his example to Olaus Magnus' map of the North. Corrections have been made, for instance the see at Hólar has been moved to its right place in the north. A few items have been taken from the Zeno map, including the seven islands off the east coast.
