A mask didn't know about

I'm reading a book called the Devlin Diary and there's reference to a type of mask I hadn't heard of before, called a vizard. I looked it up online and here's what I found:

Randle Holme described a vizard mask as a MASK 'which covers the whole face, having holes for the eyes, a case for the Nose, and a slit for the mouth, and to speak through; this kind of Mask is taken off and put on in a moment of time, being held in the Teeth by means of a round bead fastned on the in-side over against the mouth' [Holme (2000)].

Sounds delightful, doesn't it?
