Chorobates
From Wikipedia, the free encyclopedia
A chorobates (Greek χωροβἀτης from khŏros; "place" + -batos, "going") was a kind of level used in classical antiquity. composed of a double square, made in the form of a T, described by Vitruvius (Lib. viii). It is believed to be the instrument that was used to level the Roman aqueducts. Typically a staff about 4 feet tall, with crossed beams at the top. Each beam had a plumb bob at each end. Grooves were made in the top of the beams for use as sightlines. This way, right angles could be determined between two points.
