Städelsches Kunstinstitut in the context of "Blinding (punishment)"

Blinding is a type of physical punishment which results in complete or nearly complete loss of vision. It was used as an act of revenge and torture. The punishment has been used since antiquity; Greek mythology makes several references to blinding as divine punishment, which reflects human practice.

In the Byzantine Empire and many other historical societies, blinding was accomplished by gouging out the eyes, sometimes using a hot poker, and by pouring a boiling substance, such as vinegar, on them.
