This is an 18th-century Chinese hell scroll that I recently purchased. The visible area of the painting is 22.75 x 52.5-inches, not including the frame, which has been cropped out. It depicts the King of Mt. Tai (Taishan Wang), a judge who presides over the seventh of ten courts of hell in the Chinese underworld. He sits at a bench overseeing the torture of sinners in the bottom left and right corners. What I find most interesting is its tie to Chinese rebel groups, per the inscription on the middle right.

(Left column) 天運庚辰年吉月吉日

"An auspicious day and month in the Gengcheng year of the Tianyun reign era"

(Right column) 李槑清供奉

"Offering by Li Meiqing"

The Tianyun reign era was used almost exclusively by Chinese rebel groups who refused to conform to the official reign eras under the foreign-ruled Qing Dynasty (1644-1911).

See here for a larger version of the scroll.
