A "Doom painting" or "Doom" is a traditional English term for a wall-painting of the Last Judgment in a medieval church. This is the moment in Christian eschatology when Christ judges souls to send them to either Heaven or Hell. The subject was very commonly painted on a large scale on the western wall of churches, so it was viewed as people left the church, and the term is typically used of these, rather than depictions of the Last Judgement in other locations or media. Many examples survive as wall-paintings in medieval churches, most dating from around the 12th to 13th centuries, although the subject was common from the 1st millennium until (in countries remaining Catholic) the Counter-Reformation. Most dooms in English churches were destroyed by government authority during the English Reformation. The most famous of all Doom paintings, The Last Judgment by Michelangelo in the Sistine Chapel, painted in 1537 to 1541, comes at the end of the tradition, and is unusually sited on the east wall behind the altar. The term "Doom" Doom or "the Doom" was a specific term for the Last Judgement and first cited to c. 1200 by the OED ("doom", 6), a sense surviving in this artistic meaning and in phrases such as the "crack of doom" and the word "doomsday", the latter going back to Old English. The original OED in the late 19th century already described this sense of "doom" as "archaic", but it remains in use in descriptions of (mostly) British medieval churches. Purpose and iconography Dooms were encouraged by the early medieval Church as an instrument to highlight the contrasts between the reward of Heaven and the agony of Hell so as to guide Christians away from misbehaviour and sin. A Doom was usually positioned either on the rear (liturgical Western) wall, if that space was available, or at the front (chancel end) of a church, often on the Chancel arch itself so that it would be constantly visible to worshippers as they faced the altar during services. Although there are many different versions, the composition stays broadly the same. On the left side of a Doom painting (that is, on Christ's right hand) is Heaven, whilst on the right (Christ's left) is Hell. At the top of the image Jesus Christ sits in glory with his right hand encouraging the saved upward, and his left hand pointing down to
