Sansepolcro is still called "Borgo" with reference to its origin name ( "Burgus Sancti Sepulcri ": Village of the Holy Sepulchre) because it was founded by two pilgrims coming back from Jerusalem with some relics of Christ's Sepulchre in the X century.
Beyond its urban and environmental features, quite perceivable walking all its streets or squares and stopping before its several and valuable artistic monuments, Sansepolcro could be felt not only as a place to physically visit, but also as a "town of the mind", to enjoy with mind and soul.
Therefore, even in the light of its history and of the personalities who were born there, this town could be considered a new land, that is, a place to discover for the suggestions of its still pure landscape beauty, the thought of its origins and history, the memory of those who passed here their life, frequented and paid tribute to it.

First of all Piero della Francesca, who immortalized it in some of his paintings (in the panels of Baptism, Nativity, Saint Jerome and a devout, in a fresco in Saint Francis in Arezzo, that of the true Cross Examination) and in the Resurrection, a wonderful fresco which Aldous Huxley defined "the most beautiful painting in the world".
In fact, in the summer 1944, Antony Clarke fortunately remembered this definition; he was the commander of an allied artillery battery almost at Sansepolcro gates. When he was about to order the start of town bombing, Clarke suddenly stopped exactly because he reminded Huxley's words about Piero and his Resurrection. This way, the town was safe thanks to the sensitivity of a soldier fascinated by Piero and, as H.V.Morton wrote, the episode left us "a beautiful example[...] of literature power and of how pen is more powerful than sword".                

Also Alberto Burri, one of the most representative and greater artists of our times, paid tribute to Sansepolcro, by which he was fascinated thanks to Piero della Francesca's charm, as he said to me in 1992, Piero della Francesca's celebrations year.
He was author and witness of the most progressive painting languages of the twentieth century and dedicated to the ancient town and its great master of the fifteenth century, the first exhibition of his famous "sackings" in the central square of "Borgo" in 1950, even if quite extemporary and of very brief duration. On that occasion Burri employed as easels the stones of the ancient Berta's Tower, broken and lacerated, like the "sackings", under the devastating strokes of mines exploded by Germans during their escape on the 31st July 1944.

Sansepolcro has been also witness of the "new science" of Luca Pacioli, who was born there by the middle of the fifteenth century and planned a revolutionary mathematical language for business calculation and "double entry". In 1476 he wrote for Perugia University students a treatise of arithmetic and algebra; later he wrote another in Zara. He taught in Naples and Milan, where he often saw Leonardo da Vinci. His "Summa de aritmetica geometria proportioni et proportionalità" was written in vulgar, as he explained, and it was issued in Venice in 1494. A treatise of this important piece of work (Tractatus particularis de computis et scripturis) includes the first presentation of the Double Entry and Ledger, a new way of keeping accounts.
Later, in 1509, Pacioli issued the Compendio de la Divina Proportione always in Venice, a piece of work dedicated to Ludovico il Moro and written in 1498 during his stay in Milan. A treatise is devoted to polyhedron study. The tables of this work were drawn by Leonardo da Vinci.

However the town of Piero and Pacioli has always been the place of a long and fertile tradition of industry and trade activities.
Rich and blooming for clothes and colouring matters in the past (above all woad, the leaves of which were properly treated for producing "pats" to dye materials blue) , beautiful for its urban structure, mansions and the precious artistic presences, the town has always helped the birth and the fortune of undertakings, which still flourish in national and international field
