After the Romans finished with the
city, it was used as an early Christian cemetary. Among the carving still
visible on the tombs are fishes and, as pictured to the left, the
Greek letters chi, rho (X and P), alpha, and omega (A and w). Both sets
of these letters were early symbols for Christ - chi and rho for the first
2 letters of his name, and the alpha and omega for being the beginning
and the end. This ends the religion lesson for the day.
