I have one in a North African-style full-face veil, both arms raised to heaven. He's pretty nifty. I want to say he's Gripping Beast, but I'm not 100% on that.
As African Al says, that mounted cleric from the Perry Sudan range is quite cool, brandishing a sword and what looks like a jumbo sausage roll (though given he's a Muslim cleric that's probably not what it is). Even though he's from a 19th Century range I don't think there's anything glaring about him that would prohibit his use in a medieval game.
Edit: Confirmed as Gripping Beast. The Imam from the Moorish* infantry range.
*They may be Moorish, but not as moreish as a jumbo sausage roll.
