A visit to the "Temple" of Serapsis at Pozzuoli

Alan V. Morgan

One of my most treasured books is a first edition of Lyell's "Principles of Geology (being an attempt to explain the former changes of the Earth's Surface - by reference to causes now in operation)." Published in 1830 - in two volumes, although a third was added an 1833 - this was the same edition that Charles Darwin took with him on his round the world voyage of the Beagle.
