"The lyrics to the song are in old Latin, and are not unlike the riddle of the Sphynx:
the mystery of the ancient female deity, later intertwined as a sexual monster.
Here are some of the lyrics and translations" - MR

saevym atque ferum vipereumque malum
quod pinnis volitans super aethera cuncta fatigat teneat possideat
semper suis amoribus perfruatur


Loose translation: She is "A savage and serpiform creature,
flying over the aether on her wings, exhausting one and all, let him have her, let him possess her,
in her embrace of love he will stay forever."
