Lo strumento era noto in Inghilterra come [[architectonic sector]].

Description

Proportional compasses for measuring the architectural orders according to the proportions of Andrea Palladio, invented by Ottavio Revese Bruti, an architect from Vicenza. Modelled after the geometric and military compass of Galileo Galilei, the instrument is formed of two flat legs and a transverse arc bearing five sets of proportional scales, each dedicated to one of the elements of an architectural order: the arches, architraves, columns, bases, capitals and balusters of the Tuscan, Doric, Ionian, Corinthian and Composite orders. The success of the archisesto among the proportional instruments used by architects was decreed by British authors who, between 1723 and 1761, at the height of the neo-Palladian vogue, published translations and revisions of Bruti’s treatise in honour of the special interest of King George III in architecture and mathematical instruments. In Britain the instrument was known as the architectonic sector.
