It is an engrossing compendium of devices which determine time by the sun or stars. The earliest sundials known from the archaeological record are the obelisks (c.3500 BCE) and shadow clocks (c.1500 BCE). In c.700 BCE the Old Testament describes a sundial as does Roman writer Vitruvius around 15 BCE. Italian astronomer Giovanni Padovani published a treatise on the sundial in 1570 which included instructions for its manufacture. This engrossing catalogue concentrates on the half millennium from the 14th to the 19th century and presents a wealth of instruments that will both fascinate and educate the collector. It is originally published in 2007.
