On the coin of Crispus mentioned above, the _Classical Year Book_, 1911, remarked: “This is a novelty, as hitherto it has been supposed that Christian symbols did not occur on London coins of the Constantinian epoch.” “It is curious that the London Mint put Christian emblems on its coins before those of Trier, Lyons or Arles” (Oman). [Illustration: FIG. 159. ] With the coins may be associated a small silver disc mounted as the head of a pin, now in the Roach Smith collection at the British Museum. My figure is from a drawing by Fairholt, according to whom it was found in Lothbury with several other small Roman objects. It seems quite certainly to represent, as Roach Smith supposed, Constantine’s vision of the Cross in the heavens (Fig. 159). A small equal-armed cross forms the clasp of a Roman bronze chain-bracelet found in London, now in the British Museum, which can hardly be other than Christian (Fig. 160). There has been some reluctance in accepting crosses of Roman date as Christian, but the evidence of the coins should modify this. [Illustration: FIG. 160. ] [Illustration: FIG. 161. ] [Illustration: FIG. 162. ] In 1862 several ingots of pewter were dredged up from the Thames near Battersea Bridge, and in 1890 more were discovered. Two are in the York Museum and the rest are in the British Museum (_Archæol. Journal_, 48). They are stamped with the monogram of Christ in two forms, with one of which is associated the words, “_Spes in Deo_” (Fig. 161), and the name “_Syagrius_” also appears. Silver and copper ingots discovered in this country have official stamps (non-Christian), and it may not be doubted that the pewter marks were also official. A lead seal in the Reading Museum, found in the Civil Basilica at Silchester, has an XP monogram, which is very similar (Fig. 162), and this, too, was probably official. The most interesting parallel known to me of the stamps on the pewter ingots is a seal from a wine jar found at Naucratis, in Egypt (_Nau._ ii. pl. 22), where we find “_Spes in Deo_” in a circle around a cross (Fig. 163). The circular form had long been used for official stamps (cf. a brick stamp with the name of Nero in Reading Museum). Pewter ware was popular at the end of the fourth century, and this is probably the date of our ingots. The name which appears on them was in use at a late time. One Syagrius, “last of the Romans,” was driven from his kingdom of Soissons by the Franks in A.D. 480. [Illustration: FIG. 163. ] [Illustration: FIG. 164. ]
