Graffiti
Although graffiti are devoid of monumental character, writings scratched or scrawled on walls or other surfaces can be of great historical importance. Many are preserved in the catacombs and on various early Christian monuments. Especially notable are the ruins of the fine edifices of the town of Menas in the Egyptian Mareotis. The graffiti help in turn to illustrate the literary sources of the life of the early Christians.
