Brass equatorial ring with two circles signed “Lasnier à Paris”.

The meridian circle, on the signature side, bears two latitude scales from 0 to 90 (for the northern and southern hemispheres) as well as two cities with their latitude (Paris 49 – Brussels 51).

On the other side is a list of eight cities with their latitude.

The inner hour ring is graduated I to XII twice and subdivided into 15 minutes, and graduated 1 to 12 twice on the inside. It is positioned on two small supports entirely engraved with acanthus leaves.

On the back is a list of seven cities and their latitude. 

The central bridge bears the scale of the months on one side and the Zodiac on the other, with a movable cursor in the centre. Each side is decorated with acanthus leaves.

The two bridge supports are engraved with floral decoration.

There is a small mobile throne supporting a brass ring.

Superb patina.

Nota : 

– Pierre-Alexis Lasnier (active from 1734), manufacturer of scientific instruments, took over the sign from J. Lefebvre.  

– His signature is rare in the world of scientific objects.

– The “Dictionnaire des fabricants français d’instruments de mesure du XV au début du XXème siècle”, edited by Franck Marcelin, does not mention an equatorial ring signed by him.

Dimensions: diameter 9.3 cm x height 12.2 cm (with ring).

Paris circa 1734/40.
