/lit/ - Literature

Asked my fellow /x/philes, and one of them suggested I try here as well, so....

I'm thinking about making a plague doctor mask for SCA events so I can swing my censer around and mutter cryptically in Latin and spook the shit out of people. And I figure my prayer should be more of a disease-exorcism... something akin to:

'In the name of our Lord Jesus and His holy mother I command you, infernal plague, to flee this place. Amen.'

So. How do you say all that in Latin? Any collegefags here that might know? I think plague/disease is 'pestus', but beyond that I'm in the dark.
