Apocryphal Acts of the Apostles (Google Books ⧉, Amazon ⧉, Bookshop ⧉)

The Travels of Marco Polo

I do not know if the date is ascertainable of the very remarkable legend of St. Thomas in the apocryphal Acts of the Apostles, but it is presumably very old, though subsequent to the translation of the relics (real or supposed) to Edessa, in the year 394, which is alluded to in the story.
