We were very anxious to do it, and made the necessary arrangements, but our too limited time obliged us to give up the idea.

So we only groped through the dismal labyrinth of St.Callixtus, under the Church of St.Sebastian.

In the various catacombs are small chapels rudely hewn in the stones, and here the early Christians often held their religious services by dim, ghostly lights.

Think of mass and a sermon away down in those tangled caverns under ground! In the catacombs were buried St.Cecilia, St.Agnes, and several other of the most celebrated of the saints.

In the catacomb of St.Callixtus, St.
Bridget used to remain long hours in holy contemplation, and St.Charles Borromeo was wont to spend whole nights in prayer there.
