    Rocks and minerals from Mount Vesuvius

    Volcanic rocks collected by Sir William Hamilton

    The study of volcanoes was central to eighteenth-century discussions concerning the age and formation of the earth. One of the key figures in that discussion was Sir William Hamilton (1730-1803), who collected these samples from Mount Vesuvius.

    Hamilton first arrived in Naples in 1764 as George III's Envoy and remained there for 36 years. He soon became fascinated, even obsessed, by Mount Vesuvius, which erupted in 1765. Hamilton had no previous knowledge of geology, but he thought it was important to record everything he saw. He wrote regular reports on the volcano's activity for the Royal Society in London and sent samples of the lava and other material from the volcano to the British Museum. These arrived in four batches between 1768 and 1779.

    In 1776 Hamilton published his findings concerning the volcano in Campi Phlegraei, the title of which refers to the 'flaming fields' caused by the molten lava. The book contained many beautiful hand-coloured illustrations that Hamilton commissioned from the artist Pietro Fabris. It also outlined Hamilton's theory that volcanoes build up the land rather than destroying it, suggesting that the earth might be of a very great age if it was formed in this way.

    Most of the rocks Hamilton collected are dolomite or derived from dolomite and many have been cut and polished. Presumably Hamilton employed local masons to prepare them.
