An old engraving of Sibley’s cast-iron level. It is from a Victorian mechanical engineering book of the 1880s. This has a circular table and a viewing sight at one end. A plumb line below accurately fixes the level to a spot on the ground. A spirit level, bubble level, or simply a level, is an instrument designed to indicate whether a surface is horizontal (level) or vertical (plumb). Different types of spirit levels may be used by building trades workers, surveyors, metalworkers, and in some photographic applications.
