Now in the _Menologium_ of Basil we have a representation of the Exaltation of the Cross, which the patriarch is uplifting in an ambo. It is represented as a double cross made up of three pieces, not of two. A miniature of the finding of the Cross in the National Library of Paris shows the same form. Didron remarks that the cross with double branches probably originated in Greece, “for it is constantly seen in Attica, in the Morea, and on Mount Athos.” This form appears frequently on the later coins of Constantinople, and we find that most of the relics of the True Cross which still exist on Mount Athos and other places are made up with double arms. A reliquary for the fragment, said to be that which was sent to Radegunde, was preserved in the monastery of S. Cross at Poitiers in the last century. The field was of _cloisonné_ enamel, blue with here and there a red flower. A drawing of this relic, of which we give an outline,[172] shows that this fragment of the True Cross was made up in the double-armed form, which was repeated in the relic at the Ste. Chapelle.[173] Two such relics now at Venice are doubly interesting, for besides a cross of this form two supporting figures are represented which are inscribed Constantine and Helena.[174] Now Cedrenus and other late writers say that in the Kamara of the Milion were the figures of Constantine and his mother, with the cross between them. The same composition appears in the mosaics at the monastery of S. Luke. The two Venice relics bear the names of the Empresses Maria (1180) and Irene (1350). [Illustration: FIG. 14.--Showing form of True Cross at S. Sophia.] Fig. 14 represents the Poitiers reliquary; the True Cross as shown in the _Menologium_; and a cross from a late coin. We cannot doubt that the Cross at Constantinople was of this form. Was it the result of the conjunction of three pieces as mentioned by Arculph, or did the upper arm from the first represent the label? With the Cross were associated the other Instruments of the Passion--the Crown of Thorns, the Sponge and Spear, and slabs from the Tomb. The catalogue of relics by Nicholas Thingeyrensis (1200) says, “In S. Sophia is the Cross of the Lord which Helena the Queen brought;”[175] but at that time the greater part of the Cross and other relics of the Passion seem to have been transferred to the chapel in the palace of Boucoleon, where they were seen by Robert de Clari (1200). The anniversary of the day on which they were moved from S. Sophia, August 14th, was kept as a holiday. According to Paspates all the relics of the Passion were removed in 1234. Baldwin II. took the Crown of Thorns which was acquired by S. Louis. It is evident, however, from the later Pilgrims quoted below, and from Mandeville, that a part of the Passion relics remained or that others were acquired.
