Speaking of Tarandus, I came across this whilst looking for evidence of the Medieval belief in their (Tarandus') antipathy towards snakes. I'd just found out that some people keep goats in order to kill snakes, and was thinking that maybe reindeer were used similarly, given the Bestiary's report that stags kill serpents, although they probably don't snuffle them (snakes) up with their nostrils...anyway.
Slaughter for the purported libido-increasing quality of one's headgear: it's not just for rhinoceri anymore. What won't people eat if you tell them that they'll be more manly for it? I bet this is how a lot of traditional dishes started out. Primitive Viagra.
