“They call stigmata things inscribed on the face or some other part of the body, for example on the hands of soldiers… In cases where we wish to remove such stigmata, we must use the following preparation… When applying, first clean thestigmata with niter, smear them with resin of terebinth, and bandage for five days… The stigmata are removed in twenty days, without great ulceration and without a scar.”
Aetius of Amida, Tetrabiblion (c. 500)
