In ancient Roman religion, the Manes or Di Manes are chthonic deities sometimes thought to represent souls of deceased loved ones. They were associated with the Lares, Lemures, Genii, and Di Penates as deities (di) that pertained to domestic, local, and personal cult. They belonged broadly to the category of di inferi, "those who dwell below", the undifferentiated collective of divine dead. The Manes were honored during the Parentalia and Feralia in February.
The abbreviation D.M. at the top of this 3rd-century Christian tombstone stands for Dis Manibus, "to the Spirits of the Dead"
Religion in ancient Rome consisted of varying imperial and provincial religious practices, which were followed both by the people of Rome as well as those who were brought under its rule.
