A finely engraved map of the British Isles by Girolamo Porro which first appeared in Tomaso Porcacchi's 'L'Isole Piu Famose del Mondo' first published in Venice 1572. This example is from one of the following expanded editions. As might be expected for an Italian map the cartography draws more upon George Lily's exceedingly important map of 1546, rather than the more up to date Gerard Mercator wall map of 1564. Ireland though appears to derive from a third common source. In reducing the larger source map although Porro is recognised for his fine engraving here he accidentally omits London!
