MINOTAUR. BtVS Intertext/Allusion.
Monster with a bull’s head and a man’s body in Greek mythology. The Minotaur was the offspring of Poseidon’s bull and Pasiphae, the wife of Minos, king of Crete. The Minotaur was kept in the Labyrinth beneath the palace of Knossos. He ate human flesh and was fed with hostages from mainland Greece. With the help of Minos’ daughter Ariadne, the hero Theseus killed the monster.
The Minotaur is mentioned on Buffy in “Hell’s Bells” when Buffy plays for time and pretends to Anya that the minister has been called away on doctor’s business.
Buffy: You know, he’s not just a minister. He’s also a doctor. You know, he’s half minister, half doctor. He’s a mini-tor. Not of course to be confused with Minotaur, because he’s all, you know, man-ness. Doctor, minister, man. No, no bull part whatsoever.
Buffy would want to make it clear to Anya that she is referring to an ordinary human and not to a Minotaur, because various man-beasts exist in the Buffyverse. Also, some monsters on Buffy eat human flesh, and many live in dark, underground places.
