Eight specimens of pumice, lava and other volcanic rock emitted from the eruption of Vesuvius of 1779, as found by Hamilton in its aftermath.

Plate four from the Supplement to Sir William Hamilton's Campi Phlegraei, 'Fields of Flame'.

William Hamilton (1730-1803) British diplomat, archaeologist and volcanologist was elected a Fellow of the Royal Society in 1766 on the merit of his volcanic observations. He received the Copley Medal in 1770 for his 'Account of a Journey to Mount Etna'.

Pietro Fabris (1740-1792) was a British artist who accompanied Hamilton around Mount Etna, Mount Vesuvius, and Lipari islands to document volcanic activities.

Object history

The original edition of ‘Campi Phlegraei; observations on the volcanos of the two Sicilies’ was published in 1776. This Supplement was published in 1779. It is composed of observations of the 1779 eruption sent to the then President of the Royal Society, Sir Joseph Banks (1743-1820). Hamilton's observations are recorded via letters and these hand-coloured plates.
