At the close of the tenth century, when Otho III. was Emperor of Germany, a certain Hugh de Montboissier, a noble of Auvergne, commonly called "Hugh the Unsewn" (_lo sdruscito_), was commanded by the Pope to found a monastery in expiation of some grave offence. He chose for his site the summit of the Monte Pirchiriano in the valley of Susa, being attracted partly by the fame of a church already built there by a recluse of Ravenna, Giovanni Vincenzo by name, and partly by the striking nature of the situation. Hugh de Montboissier, when returning from Rome to France with Isengarde his wife, would, as a matter of course, pass through the valley of Susa. The two--perhaps when stopping to dine at S. Ambrogio--would look up and observe the church founded by Giovannia Vincenzo: they had got to build a monastery somewhere; it would very likely, therefore, occur to them that they could not perpetuate their names better than by choosing this site, which was on a much-travelled road, and on which a fine building would show to advantage. If my view is correct, we have here an illustration of a fact which is continually observable--namely, that all things which come to much, whether they be books, buildings, pictures, music, or living beings, are begotten of others of their own kind. It is always the most successful, like Handel and Shakespeare, who owe most to their forerunners, in spite of the modifications with which their works descend. Giovanni Vincenzo had built his church about the year 987. It is maintained by some that he had been bishop of Ravenna, but Clareta gives sufficient reason for thinking otherwise. In the "Cronaca Clusina" it is said that he had for some years previously lived as a recluse on the Monte Caprasio, to the north of the present Monte Pirchiriano; but that one night he had a vision, in which he saw the summit of Monte Pirchiriano enveloped in heaven-descended flames, and on this founded a church there, and dedicated it to S. Michael. This is the origin of the name Pirchiriano, which means [Greek text], or the Lord's fire.
