Ave Satani

"Ave Satani" is the theme song to the 1976 film The Omen, which is composed by Jerry Goldsmith. The Omen won the Academy Award for Best Original Score, with Ave Satani nominated for Best Original Song.

History
The Latinized title translates to "Hail Satan" in English. In an interview, Goldsmith says that his idea was to create a kind of Satanic version of a Gregorian chant and came up with ideas while talking with the London choir-master of the orchestra who was helping him. He decided to create something like a Black Mass, inverting Latin phrases from the Latin Mass. The choir-master, according to Goldsmith, was an expert in Latin and helped him come up with phrases; instead of saying "Hail Mary", they decided on "Hail Satan", and so on. The song contains various Latin phrases inverting Christ and the Mass, such as "Ave Versus Christi", meaning "Hail Anti-Christ", and "Corpus Satani", an inversion of "Corpus Christi", the body of Christ. The resulting lyrics are an inversion of the Roman Catholic rite of the consecration and elevation of the body and blood of Christ during the Mass.

A version of the song has been produced by the band Fantômas, who altered some of the lyrics to mean "smallest blood, body spirit" rather than "we drink the blood, we eat the flesh," and adding the word "rotted". Other versions of the original song have been performed by the Italian vocalist Servio Tulio, and by Gregorian. The song has been used in mixes of sinister music including the album Oculus Infernum by Van Helsing's Curse, featuring Dee Snider.
