Manes

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 theologian Augustine, writing about the subject a few centuries after most of the Latin pagan references to such spirits, differentiated Manes from other types of Roman spirits:

"Apuleius says, indeed, that the souls of men are demons, and that men become Lares if they are good, Lemures or Larvae if they are bad, and Manes if it is uncertain whether they deserve well or ill. For, however wicked men have been, if they suppose they shall become Larvae or divine Manes, they will become the worse the more love they have for inflicting injury; for, as the Larvae are hurtful demons made out of wicked men, these men must suppose that after death they will be invoked with sacrifices and divine honors that they may inflict injuries. But this question we must not pursue. He also states that the blessed are called in Greek eudaimones, because they are good souls, that is to say, good demons, confirming his opinion that the souls of men are demons."

Latin spells of antiquity were often addressed to the Manes.
