A second medal, which bears the name of Gaudentianus on the obverse and Urbicus on the reverse, depicts seemingly on one face the sacrifice of Abraham; on the other apparently a shrine or altar, above which three candles are burning, towards which a tall figure carrying a chalice in one hand is conducting a little child. The scene appears to represent the consecration to God of the child as an oblate by his father before the shrine of some martyr, a custom for which there is a good deal of early evidence. Other medals are much more simple, bearing only the Chi Rho with a name or perhaps a cross. Others impressed with more complicated devices can only be dated with difficulty or, as in the case particularly of some representations of the adoration of the Magi which seem to show strong traces of Byzantine influence, belong to a much later period.
