The Robbers in the Garden
The one incident preserved in the saint's life concerns a band of robbers who entered the monastery garden intending mischief. By the power of his prayer, Silvanus held them fast to the spot, and for three days they were not able to move. Only after they repented did the monk release them.
The episode is the basis for Silvanus's commemoration as a wonderworker and stands as the defining feature of his entry in the synaxarion, of which almost nothing else of his biography survives.
