Lintel, pediment, and tympanum A lintel is a horizontal beam connecting two vertical columns between which runs a door or passageway. Because the Angkorean lacked the ability to construct a true arch, they constructed their passageways using lintels or corbelling. A pediment is a roughly triangular structure above a lintel. A tympanum is the decorated surface of a pediment.
