L'arcano incantatore, internationally released as The Mysterious Enchanter and Arcane Sorcerer, is a 1996 Italian horror film directed by Pupi Avati and set in the 18th century.

The seminarian Giacomo Vigetti is forced to leave Bologna to avoid conviction, after having impregnated a girl and inducing her to have an abortion.

The latter lives alone in an isolated house, surrounded by the volumes of a gigantic library, and Giacomo must replace Nerio, his previous assistant, who died in unclear circumstances and about who ambiguous rumors circulated.

The two make a kind of friendship, and the boy quickly convinces himself that in the telepathic and magical searches of his master there is nothing sinister.

One night Giacomo exhumed Nerio's body and brought it to the parish priest of the town; here he discovers with amazement that the corpse is that of the monsignor.
