Passage of the precious Relic from the Apostles to Patriarches
Just like here the great Pearl diminish, the Holy Shroud became a Mandilion! 

    In Arian Baptistery of Ravenna of the sixth century (decorated by the Orthodox) St. Paul show Scriptures on the cassock; for this reason, the Pearl here is not properly a "stone altar" but the Centre itself! In the same Dark church, the crucifix have the wound in the chest right, foot on an asymmetric hassock (not imagining the artist it was used a single nail). The beard is divided into two; we see some intumescences, also at the wrists, because the nails are imagined on the palm, as if to assume here an "hematic hydrosis", and also small drops of blood on the forehead; all this and other is disposed as in the Shroud: the artist had seen properly this, or the Christ! Of annotations above there are documents of the fourth century, for example a comedy that was ascribed Gregory of Nazianzus (384 AC) in the major parts, "Christus Patiens", where the author assert that Jesus was crucified naked with three nails and he after died was deposed with the blood still streaming from the wound to the side, and was enveloped in some towels. The last assertion go back to the Gospel of St. John; the other (of three nails) will be disclosed only in the Middle Ages with the exhibition of the Shroud whole, however, into the 450 AC, this is reported by at least two other writers: Nonnus (Egyptian) and Socrates (Turkish) and this is the proof that the Shroud in the fourth century, though few visible, already is existed. Socrates continued his "Ecclesiastical History" perhaps for a suggestion of Theodore Mopsuestia, disciple of Chrysostom. Nonnus has paraphrased the IV Gospel and he lived to Akhmi'm, where in 447 Nestorius (†451) was exiled (he have described the human nature and the godlike nature of Jesus as two distinct subjects). Nestorius is born in Kahramanmaraç near Nazianzus: from here to the common knowledge of the Holy Shroud the step is short! The same (or another?) Nonnus, monk in Tabenna of the Nile, was the patriarch of Edessa (448-471 †) pending the final decision on Ibas (435-457 †) accused of Nestorianism.

    The Nazianzen was an ascetic and often he retreated in hermitage; Bishop of Sasima (at Nyssa, where was the other Gregory) he fought the Aryans, but disgusted by the schism of the 382 he retired to Nazianzus, actual Konya (shown here in the Christian Map) not far from S. Daniel, and it is not a coincidence! Apart from the brilliant Dissertations of S. Cyril of Jerusalem, focused on the Shroud, some strong recalls exist on the Shroud also for St. John Chrysostom (381) St. Gregory of Nyssa (379) Eusebius of Caesarea (325) Epistula Smith & Pope Eusebius (309-335) C-46 of the Liber Pontificalis. In particular, while he acknowledge the existence of the Shroud, the Monophysite Eusebius, an opponent to the exposure of Christ image, he does not furnish information of the "Portrait of Christ" existent in the Archive of Edessa, seen by him thus as Ephrem the Syrian, the author of the "Doctrine of Addai". This is a well known strategy for fights against the Arians, a fight that was emphasized in the fifth century against the Nestorians!
