The Ecclesiastical History of Sozomen

About the same period, the queen was attacked with a disease, and Tarbula, the sister of Symeon the bishop, a holy virgin, was arrested with her servant, who shared in the same mode of life, as likewise a sister of Tarbula, who, after the death of her husband, abjured marriage, and led a similar career. The cause of their arrest was the charge of the Jews, who reported that they had injured the queen by their enchantments, on account of their rage at the death of Symeon. As invalids easily give credit to the most repulsive representations, the queen believed the charge, and especially because it emanated from the Jews, since she had embraced their sentiments, and lived in the observance of the Jewish rites, for she had great confidence in their veracity and in their attachment to herself. The Magi having seized Tarbula and her companions, condemned them to death; and after having sawn them asunder, they fastened them up to poles and made the queen pass through the midst of the poles as a medium for turning away the disease. It is said that this Tarbula was beautiful and very stately in form, and that one of the Magi, having become deeply enamored with her, secretly sent a proposal for intercourse, and promised as a reward to save her and her companions if she would consent. But she would give no ear to his licentiousness, and treated the Magi with scorn, and rebuked his lust. She would rather prefer courageously to die than to betray her virginity.

As it was ordained by the edict of Sapor, which we mentioned above, that the Christians should not be slaughtered indiscriminately, but that the priests and teachers of the opinions should be slain, the Magi and Arch-Magi traversed the whole country of Persia, studiously maltreating the bishops and presbyters. They sought them especially in the country of Adiabene, a part of the Persian dominions, because it was wholly Christianized.
