So you're a lion and you've somehow fetched up in England in the 13th century.
You're housed on the Tower of London grounds, where hopefully you can at least catch one of those ravens that makes such a point of wandering about. You're part of the Royal Menagerie, but that doesn't mean your house is nice or even very big. In fact it's probably about 6 meters by 6 meters, and you don't get out much except to be baited in lion-vs-dog fights.
And when you die, they dump you unceremoniously in the moat.
You know - this kind of thing is why I find medieval studies so blasted grim.
About that moat? In the 30's excavations turned up two lion skulls, and recent carbon dating reveals one is dated AD 1420-1480, the other AD 1280-1385. Thing sdid get better for the lions and other exotica at the Royal Menagerie n later centuries. Find out all about it here.
