Fiesole is a town on a hill overlooking Florence and the Arno valley in Tuscany. It dates from the eighth century BC. Sections of Etruscan wall, Roman baths and a Roman theatre have survived, as have notable medieval churches. Ruskin, who spelt the name Fésole, recalls his first visit of 1845 in Praeterita (1885-89). In The Laws of Fésole (1877-78) he describes a re-mapped world in which the first meridian, which he names Galileo's line, passes through Fiesole ( Works, 15.442).
