Discussion
There are four Greek pre-Metaphrastic versions of the martyrdom account of Iakobos the Dismembered, the martyr of Persia: BHG 772, 772a, 772b, and 772c. Version BHG 772c is still unedited. According to Paul Devos (1953; 1954), the editor of the three versions, the Greek texts are based on a Syriac original (for which see E07154, with a summary of the Syriac text dating from the 5th/6th century). There is also a Coptic story related to the same martyr which goes back to the 6th century (see E07053).
In broad outline, the three edited Greek versions of the Martyrdom follow the Syriac one with only one main difference: according to the Syriac text, after the beheading of the martyr, fire from heaven comes upon his remains and the bloodstained ground. This miracle is completely omitted from the Greek texts.
Unsurprisingly, the translation of the martyr's remains from Persia to Jerusalem and then from Jerusalem to Oxyrhynchos in Middle Egypt, as presented in the Coptic text, is absent from all the Greek versions (as also from the Syriac).
