Carpentry has a long history dating back to ancient civilizations. The early Chinese are believed to have developed woodworking as far back as 720 BC, with craftsmen like Lu Ban credited as originators. The Egyptians were among the first to apply finishes to woodwork and use veneering in panels. This knowledge spread to other ancient civilizations like the Greeks, Babylonians, and Persians. Early buildings were constructed with wooden posts set in the ground or on concrete footings, with markings used to check vertical alignment and heights leveled for horizontal components.
