Piero della Francesca
The Piero della Francesca Trail is an excursion which traces the works created by Piero della Francesca in Arezzo, Monterchi, San Sepolcro (his birthplace) and Urbino. To his contemporaries, Piero was admired as a mathematician and geometer as well as a painter, and today his paintings are celebrated for their serene humanism and use of geometric forms.
