The present instrument is dated 1713, and also dedicated to the Duke of Orleans. The title and dedication are surrounded by an elaborate cartouche featuring the coats-of-arms of the Duke of Orleans, several scientific instruments including an armillary sphere, a quadrant, a telescope, a pair of compasses, and two putti surveying the heavens through telescopes. As the title suggests, the instrument depicts a heliocentric universe in accordance with Copernicus. At the centre is the sun with each planet’s orbit delineated, from Mercury to Saturn, together with its title and planetary symbol. Between the orbits of Jupiter and Saturn are placed the signs of the zodiac, together with the orbital period for each planet through the zodiac and their aphelion (i.e. the point in their orbit where they are furthest from the sun). There are also letters placed upon each orbital path: ‘S’, ‘M’, ‘D’, and ‘A’; ‘A’ & ‘D’ mark the point of the planet’s ascension and declination, with ‘S’ and ‘M’ marking planetary nodes.
Rare. We are only able to trace one institutional example of the work, that in the Bibliotheque Nationale de France (FRBnF42097471).
