Pietro Antonio Solari

Pietro Antonio Solari (c. 1445 - 1493), also known as Pyotr Fryazin, was a Swiss Italian architect and a secret member of the Assassin Order.

Pietro was killed in May of 1493 by Tsar Ivan III's men, though the Tsar blamed another Assassin by the name of "Aristotele". The Assassins only found out about this ten years later, when Ezio sent recruits to investigate his death.
