Description

Instrument for architectural measurements and surveying formed of a simple board with sheets of drawing paper on which the surveyor traced the sighted lines directly, constructing one by one the various triangles needed for calculating proportionally the estimated distances. A similar board was described already in the thirteenth century by Domenico da Chivasso, but the device is called by this name only in the treatise of Francesco Pifferi from Siena.
