An insight into the life and work of 15th-century Italian painter Piero della Francesca. Tim Marlow travels through the villages of Tuscany and Umbria to uncover the enigmatic artist responsible for religious works including The Baptism of Christ, and famed fresco cycle The Legend of the True Cross, which were later cited by masters such as Cezanne and Picasso as major influences on their work. Only 26 of his pieces have survived the centuries since his death in 1492, and one - The Resurrection - is still housed in Sanselpocro, Piero's home town, but it was not until long after his demise that his fame spread worldwide.
