Nestor of Thessalonika
Saint Nestor of Thessalonika was a companion of Saint Demetrius the Wonderworker. Having been moved to act against the mighty Lyeios, a most feared gladiator who mocked and tormented the Christians in the arena, Nestor went to see the imprisoned Saint Demetrius and asked for his blessing to fight and defeat Lyeios. With the blessing of the saint and faith in God he entered the arena and mortally struck Lyeios.
Maximian was angered by this and ordered that Nestor be slain with his own sword in 290.
