Bull's Teeth

My guide made a dismissive noise. "After, before. . . these things all go back. They talk about the labyrinth of Minos, but that was nothing by comparison to this. Just some tunnels with a horn-headed fellow wandering lonely and scared and hungry. He wasn't really a bull head. You know that?"
"How do you know?"
"Teeth. Bulls and cows are ruminants. They don't eat flesh. The minotaur did."
"Hadn't thought of that."
"People don't."
