Mine is pic rel. Saint Anastasius of Persia, also known by his native name Magundat, was a Zoroastrian soldier (born of a magician) in the Sasanian army who later became a convert to Christianity.

In 614 CE, King Khosrow's forces captured Jerusalem and seized the relic of the True Cross. Magundat was part of this campaign and was deeply impressed by the relic and the Christians' devotion. This experience prompted him to inquire about the Christian faith. He left the army, was baptized in Jerusalem by Patriarch Modestus, and was given the name Anastasius ("resurrection").
