Gervase certainly never saw any of these relics, so derived his stories from other sources. The Edessa one may have come from the 10th or 11th century Codex Vossianus Latinus, which quotes Christ’s words to Abgar (in a letter) as: “If you truly want to see my face in actuality, I send you this linen cloth, on which you will be able to distinguish not only the form of my face, but my entire body, in its divinely transformed [human] state.” However, this is confused a little later when we learn that: “On the holy day of Easter, it divided itself into several different ages, being at the first hour of the day an infant, at the third truly a child, and at the sixth an adolescent, while at the ninth it appeared fully grown, in the state in which the son of God came to his passion and endured the suffering of the cross for the weight of our wicked sins.”
There is no possibility that this can refer to the Image of Edessa, even in the unlikely event that this cloth had been, as the Codex claims, still kept, as it has been from the earliest times, in the city of Edessa. What it may refer to is a mythical origin for some Byzantine liturgy, involving large cloths bearing images of Christ in infancy or death (melismos and epitaphios), the earliest versions of which seem to have looked more or less identical, and may have been interchanged during the course of some eucharistic rites.
This legend might in turn derive from the 8th century John Damascus’s De Imaginibus, where a full-length image of Christ is also mentioned. However this is so different from all the other descriptions of the Image of Edessa that it is more likely to be a conflation of that image with the “Image of God Incarnate”, otherwise called the Image of Camuliana, another acheiropoietos image in Constantinople, from yet another tradition.
That there were full length images of Christ in Constantinople is, I think, not at all unlikely, but attempts to link them to either the image of Edessa, beforehand, or the Shroud, afterwards, are, I think, insufficiently justified.
