The names appear to have been added in the thirteenth century; the letters are Latin. There are three rows of the enamels. At the top, upon the curve, are four figures in roundels "SS. Andreas, Blasivs, Petrvs," and the Archangel Michael. The nimbi are blue-green, the figures red.
The others are: an Apostle with a roll, "Santvs Petrvs"; a bishop, "Santvs Blasivs"; "Santvs Matevs" with a book in the left hand; "Santvs Jacobvs" with a roll. The third row has eight circular enamels, alternately figures and ornaments.
