 The first mention of Sant'Oreste is made by Benedict of Soracte in his "Chronicon" in 747 AD, in which he mentions "Curtis Sancti Heristi".One source states that the toponym derives from the family of the Aristi or Edisti.A member of this family, Saint Orestes (Edistus, Sant'Edisto, Sant'Oreste) was martyred for his faith around 68 AD.
