It attracted so little attention, that nearly three hundred years elapsed before any European work on the subject appeared. In 1496 Paccioli published his book entitled "Arte Maggiore," or "Alghebra." In 1501, Cardan, of Milan, gave a method for the solution of cubic equations; other improvements were contributed by Scipio Ferreo, 1508, by Tartalea, by Vieta. The Germans now took up the subject.
Piero della Francesca was born about 1416 at the little town of Borgo San Sepolcro, just within the borders of Tuscany towards Arezzo. He was a great student of perspective, a friend of mathematicians, of Fra Luca Paccioli, for instance, who later became the friend of Leonardo da Vinci. His work has force, and is always full of the significance of life.
