Saint Theonestus of Vercelli is venerated as a martyr by the Catholic Church. Theonestus may have been a member of the early Christian community in Vercelli living in an era earlier than that of Eusebius of Vercelli. Theonestus may have been a martyr whose relics were buried in the cemetery where other Christians were buried outside the city walls. It is believed that his whole body was conserved in the tomb dedicated to him.
