Sylvester Gozzolini, Italian founder of the Sylvestrines (born 1177)

Silvestro Guzzolini was an Italian Catholic priest and the founder of the Silvestrini. He served as a canon in Osimo but respectful rebukes of his bishop's inappropriate conduct led him to leave for a hermitage before the bishop could strip him of his position. He remained in his hermitage with a determination to found a religious congregation and based it upon the Order of Saint Benedict after having a dream of Benedict of Nursia. His order received papal approval from Pope Innocent IV which allowed his order to expand across Italian cities to a significant degree.

The Sylvestrines are a congregation of monks of the Order of St Benedict who form the Sylvestrine Congregation. The Sylvestrines use the post-nominal initials O.S.B. Silv.. The congregation was founded in 1231 by Sylvester Gozzolini. They are members of the Benedictine Confederation. The congregation is similar to others of eremitical origin, in that their houses are not raised to the status of an abbey, which would entangle the monasteries more strongly in the affairs of the world. The congregation, though, is led by an abbot general, the only abbot it has, who supervises all the houses of the congregation.
