Between the third and the seventh century,  over six million pagan, Jewish and Christian burials took place in the catacombs beneath Rome. It is also where persecuted Christians were able to bury their dead in secret.  Some of the burials were very elaborate with rooms carved out of the rock, decorated with frescoes. Most examples of  Christian art before about 400 AD are here - images and sculptures of the gospel stories and scriptures.
