Volterra's 13th-century Franciscan church, just inside the Porta San Francesco, has one overwhelming reason to visit: Halfway up the right aisle is the Cappella Croce del Giorno, frescoed with the “Legend of the True Cross” in medieval Technicolor by Cenni di Francesco in 1410. While not nearly as beautifully executed as Piero della Francesca’s telling of the same story in Arezzo, Cenni’s version of this popular medieval tale is quite compelling, especially with his knack for reproducing the dress and architecture of his era. Though the artist worked for some of Florence’s most important families, this is his only remaining signed work. It shows a unique style: golden backgrounds, flattened space, and elongated figures with elegant features.
