Description
Antwerp mathematician and instrument maker Michiel Coignet invented the reigle platte in the late 16th Century or early 17th Century. Like the sector, from which it was developed, the reigle platte is used to solve mathematical equations.
The layout of this particular instrument is based on the scales illustrated and described in Geometriae Practicae, pars Tertia by Adrian Metius (1571-1635) in 1625.
