user48771: I asked this question a while back:
The afflictions of Tarrare
It was fairly well received judging by votes, and think the subject matter is quite intriguing.
However, where I am normally able to bounty questions for which there is no 'canonical' answer, I was not given the option here. 
Is there a reason I could never add a bounty to this? 

user27148: See How does the bounty system work? from the main meta for more information on bounties.

You must have at least 75 reputation to start a bounty, and at least as much reputation as the bounty amount.
