The outer doors of the porch at the south end of narthex are still more remarkable. The panel margins are made up of cast bronze decorated with meanders, frets, and leaf mouldings, very delicately modelled in high relief. These are evidently of antique workmanship, possibly they may be as late as the fourth century, but they can hardly have been wrought later. The ancient doors have been enlarged by adding outer margins, consisting of later relief work, and flat metal studded with little leaf ornaments which form the heads of pins. The panels have been filled with plates of bronze, which bear an inscription ingeniously made up of monograms, arranged on crosses in circles; these are deeply engraved into the metal plates and filled with silver. It is interesting to find here an example of the damascened work of which some of the doors in Italy brought from Constantinople are such remarkable specimens.[365] The letters are beautifully designed, and in all cases the horizontal arm of the cross is above the centre of the circle in which it occurs. Good engravings of these doors are given by Salzenberg, who however incorrectly transcribes and arranges the inscription on the panels. Of this we here give a corrected version, Fig. 69. (The top line in the figure is actually above the right-hand monograms.) The inscription has been deciphered in the previously mentioned _Transactions_ of the Greek Syllogos at Constantinople.
