At the Guildhall Museum are two small terra-cotta lamps (Nos. 17 and 18), each having the Christian monogram in the centre (Fig. 164). These are not of British make, but they may have been imported in the Roman age. (A lamp which Sir L. Gomme made much of, with a little view of a city on it, was also of foreign origin, and there is no reason to think that the view had any connection with London.) Two other lamps in the Guildhall collection (Nos. 54 and 117) are described as having “limbs of cross on body, perhaps early Christian,” but I have not found these and some other objects which it is said may possibly be Christian. In the description of Wren’s finds on the site of St. Paul’s, given in _Parentalia_, is mentioned “a sepulchral earthen lamp figured with two branches of palms, supposed Christian.” Comparing the description with Figs. 165 and 166 there cannot be any doubt that Wren’s lamp was Christian. In the British Museum is a little rough lamp found at Tidworth, Wilts, which has a pair of palm branches, and I think that there is another in Canterbury Museum; the former is so like others from Syria in the Early Christian Room at the British Museum that there cannot be a doubt that it is not a native work; possibly it was brought back by a pilgrim from the Holy Land. Fig. 165 illustrates the seal of a ring found at Fifehead Neville, Dorset, now in the British Museum; on it we find the sign of Christ in the later form (in which the X has become a cross) surmounted by a dove, and between two palms. It means something like “the Believer resting on the victorious Cross of Christ.” The earlier form of the monogram was made of the first two letters of the name Christ, XP; the later form was formed by a cross and XP or P, and this seems to have meant the Crucifixion. [Illustration: FIG. 165. ] These comparisons will help to interpret a fascinating fragment of a symbolical design engraved on a glass cup found at Silchester. Here, instead of the sign for Christ, we find the upper part of a letter, which can hardly have been anything else than T, for nothing else would be central in the design, and in place of the dove we have a fish. T was the early form of the sign of the cross, and is found several times in the Catacombs; the fish is a rebus for the words Jesus Christ, God’s Son Saviour (ΙΧΘΎΣ); the palms are again signs of victory. It seems to be an early symbolical representation of Christ on the cross, and one of the most interesting which exists (compare Figs. 46 and 47 in the British Museum _Guide to Christian Antiquities_). Another tiny fragment of the same glass has the letter O on it, and there must have been some short inscription as well as the fish symbol and palms (Fig. 166).
