Conversion and Martyrdom
The synaxarion records that Memelchtha had been a priestess of Artemis before embracing Christianity. Her sister, already a Christian, was the human agent of her conversion, convincing her to accept baptism.
Her death followed directly upon her baptism. When pagans saw her still wearing the white baptismal robe — the customary garment of the newly illumined — they responded with violence and stoned her. The sources place her martyrdom in 344.
Historical Context
Memelchtha suffered during the great persecution of Christians in the Sasanian Persian Empire under Shapur II (reigned 309–379). After the Roman emperor Constantine the Great embraced Christianity, Shapur came to regard his Christian subjects as potential agents of a foreign rival, and the persecution that followed is reckoned among the most intense of the Sasanian period.
The persecution was triggered when Shapur imposed a heavy tax on Christians to finance his war against Rome. When the Patriarch Shemon Bar Sabbae and his clergy refused both the tax and pressure to convert to Zoroastrianism, a long cycle of martyrdoms began. The fifth-century historian Sozomen reckoned the number of named men and women martyred in this period at upwards of sixteen thousand, and Shapur's successors in the patriarchate, Shahdost and Barba'shmin, were also put to death. Memelchtha's martyrdom of 344 falls within this period.
Memelchtha is an obscure saint: no extended hagiography survives beyond the brief synaxarion notice. The wider account of the Shapur II persecution supplies the historical setting rather than further detail about her life.
