In Ancient Rome, the genius was the guiding or "tutelary" spirit of a person, or even of an entire gens. A related term is genius loci, the spirit of a specific locale. In contrast, the internal driving force within all living things is the animus. A specific spirit, or d?mon, may inhabit an image or icon, giving it supernatural powers.
A comparable term from Arabic lore is a djinn, often Anglicized as "genie". Note, however, that this term is considered a false friend, not a cognate by most Anglo-American anthropologists. Recent work by Russian, Romanian, Italian and a few American linguists may return the word to cognate status.
