A Louis XVI gilt bronze white marble planetarium clock, made by Augustin (II) Fortin, c 1770. The gilt bronze mounted white marble plinth is centred by a circular white enamel clock dial with black Arabic numerals for the hours, outer red Arabic numerals for the minutes and inner red Arabic numerals for the 31 days of the month with a fine pair of pierced gilt brass hands for the hours and minutes and blued steel pointer for the calendar indications. The fluted plinth case is of ovoid columnar form with scrolled sides on a shaped stepped base with pierced foliate frieze on turned feet. The case is surmounted by a rotating terrestrial globe inscribed on a plaque on the globe Chez le Sieur Fortin Ingenuera Pour Les Globes et Spheres Rue de la Harpe au Coin de la Rue du Foin, and further inscribed on a silver plaque attached to the globe Paris, having a golden sun and long pointer to indicate sunrise and sunset in Paris. The globe in its turn is surmounted by a rotating silver lunar ring inscribed with Arabic numerals 1-29 ½ for the lunar days in the month and Nouvelle Lune/Dm Quartier/Pleine Lune, issuing a small blue moon sphere suspended from a silvered band, with a shaped silver hour chapter ring around the globe marked twice 1-12, the arched brass ring around the globe engraved Sud/Zenith/Nord as well as engraved on both sides between the south and zenith markings Medi pour tous les peuples qui sont de sous ce meridian and further engraved with the symbols of the seven days of the week as well as the numbers 21/23/18/20/21/21, the horizontal brass ring around the globe engraved Oriente Leve du Soleil and Occident Couche du Soleil. The eight-day movement with hour and half-hour striking independently powers the arbor for the rotation of the globe. • Height: 53 cm. • The maker, Augustin II Fortin (d. 1784), descended from a family of clock and watchmakers and was himself a master clockmaker, renowned for his astronomical clocks and armillary spheres as well as his celestial and terrestrial globes. As evidence of his prowess in this latter field Fortin often signed his work as ingénieur or as here ingenuera for globes and spheres. Having been received as a maître in June 1769 Augustin II firstly worked independently at rue du Petit-Lion, he then went into association with his father and subsequently took over the family business at rue de la Harpe in 1778. Such were his talents that Fortin enjoyed the patronage of the king as well as other collectors and connoisseurs of science, astronomy and clocks. A number of examples of his own and his firm’s work can be found today in the Musée des Arts et Métiers Paris at the National Maritime Museum London and at the Walters Art Gallery Baltimore. The Musée des Arts et Métiers houses, for instance, a planetarium, a celestial globe, three terrestrial globes, one of which is also known as a tellurium or loxocosme. The latter demonstrates the movement of the earth, the seasons and the unequal days. Literature: Pierre Kjellberg, Encyclopédie de la Pendule Française du Moyen Age au XXe Siècle, 1997, p. 188, pl.
