AMESS (Ammis, Aumuses)
A hood of fur worn by canons, intended as a defence against the cold while reciting, the points coming down in front like a stole. The colour was usually grey, but for the cathedral chapter, white ermine. The fur was attached to a fabric with the fur inside. It is quite distinct from the A mice. ————————
