The document discusses medieval depictions of heaven and hell that were featured prominently in churches through paintings and carvings. These "Doom Paintings" graphically depicted visions of hell and scenes of sinners being punished or saved by Jesus. Many of the paintings were destroyed during the Protestant Reformation in the 1500s-1600s. One well-preserved example can be seen in a 12th century painting uncovered in an English church dating back to Saxon times.
