Stereotomy (Greek: Στερεός "solid" et Τομή "cut ") is the set of geometrical knowledge and techniques of drawing and cutting the blocks of stone and their assembly into complex structures (wall, vault, arch, etc..) related to architectural construction. Stereotomy represents the alternative to building techniques based on the use of small pieces of stone or brick, which make up the complex geometry structures and sometimes due to its small size and joints.
