Observations on the temple of Serapis at Pozzuoli near Naples : with an attempt to explain the causes of the frequent elevation and depression of large portions of the earth's surface in remote periods and to prove that those causes continue in action at the present time : with a supplement of Conjectures on the physical condition of the surface of the moon
Babbage's privately printed 1847 London treatise examines the Serapis temple at Pozzuoli near Naples, arguing for repeated land elevation and subsidence, and addresses fellow geologists and natural philosophers. The pictures are plain line diagrams: a cross-section of a standing column over strata, hatched and wavy layer bands with a fault line, and a sketch map of a shoreline with ruins, offering a designer clean schematic structures for technical diagrams.
