Mount Etna. Frontispiece of volume two (1832) of 'Principles of Geology' by Charles Lyell (1797-1875). This work established the principle that geological changes acting over long time periods have shaped the landscape. The example here is Mount Etna,a volcano on the Italian island of Sicily. This is the eastern side of the volcano and the Valle del Bove (Valley of the Ox),a enormous amphitheatre of cliffs and peaks created by a catastrophic collapse of this flank of the volcano in around 6000 BC. Lyell has labelled the volcanic peaks and other features,with the active summit cone at centre | |
