Another popular ancient version from the Syriac tradition replaced Helena with a fictitious first-century empress named Protonike, who is said to be the wife of emperor Claudius.[14] This story, which originated in Edessa in the 430s,[15] was transmitted in the so-called Doctrina Addai, which was believed to be written by Thaddeus of Edessa (Addai in Syriac texts), one of the seventy disciples.[16]
