Butterfield dial

Butterfield dial for latitudes 40°-60° North. Standard three-scale dial (see related terms) except for the following details:-

The compass has cardinal, quadrantal and intermediate points; with the cardinal points named in French. North is offset 8° West of North to allow for magnetic variation but the compass has been inverted. The back of the dial-plate is filled with a table of latitudes in two columns, for example: 'Paris 49', 'Londres 52' and 'Madrid 41'. The case is octagonal and made of black fishskin with green velvet lining and a brass push-button clasp.

Signed 'CHAPOTOT A PARIS', this is a typical Butterfield dial with latitudes provided for various towns in France and several in the rest of Europe. There were two Chapotots working in Paris in the last quarter of the 17th century - Louis and Jean - but it is not clear which of them was responsible for the production of these Butterfield dials.
