I don't have sufficient context to write an accurate overview based solely on what you've provided. The image caption only indicates a historical artwork depicting someone being healed of possession, but doesn't contain information about what exorcism actually is, how it's practiced, or why it matters. To write an accurate, factual overview as requested, I would need additional source material that explains exorcism itself.

Exorcism () is the religious or spiritual practice of evicting demons, Djinns, or other malevolent spiritual entities from a person, or an area, that is believed to be possessed. Depending on the spiritual beliefs of the exorcist, this may be done by causing the entity to swear an oath, performing an elaborate ritual, or simply by commanding it to depart in the name of a higher power. The practice is ancient and part of the belief system of many cultures and religions.
