Hand-coloured etching by Peter Fabris (active 1768-1779) and taken from William Hamilton's (1730-1805) studies of Italian volcanoes, 'Campi Phlegraei' (published in Naples, 1776). All land shown, including the islands, is of volcanic origin. Based on letters to the Royal Society, 'Campi Phlegraei' was a more precise account of the nature and effects of volcanic activity than had previously existed and illustrated Hamilton's claim that volcanoes were creative rather than destructive natural forces.
