Tyromancer

In college my roommate had a dictionary that had the word “Tyromancer”, defined as “someone who fortells the future through cheese”. I’ve heard of using tea leaves, but cheese!?! Was this common at any point in time and, if so, who did it and what cheese worked best?

IIRC, this was a fairly standard dictionary (like a Webster’s) and not an OED or “dictionary of funny words that no one uses”. I can’t find this word through internet searches.

No type of cheese worked best. No type of cheese worked at all.
