Small silver mounted mother-of-pearl and tortoiseshell pocket calendar.
Oval in shape, it opens on a hinge and reveals a mother-of-pearl plate engraved with three circular dials surrounded by foliage and the signature “De la Salle fecit”. Each dial has a small silver mobile index in the center:
– The upper dial near the hinge corresponds to the months of the year. It consists of 2 circles divided into 12 sectors with a rosette in the center. The outer circle corresponds to the months engraved with their first letters in French counter-clockwise (Jan, Feb, Ma, Av, Ma, Ju, Juil, Ao, Sep, Oct, No, De) and the inner circle corresponds to the duration of each month in days (28, 30 or 31).
– The lower left dial corresponds to the number of days in the month and is engraved from 1 to 31 (clockwise) with a large rosette in the center.
– The lower right dial corresponds to the days of the week engraved (clockwise) with their first letters in French (lund, mar, mer, Jeu, Ven, Sam, Dim).
The silver hinge, fitted with a suspension ring, has the particularity of being in the shape of a fleur-de-lis, which is very unusual. This type of hinge is found on very rare black chagrin cases of exceptional sundials made in the 1630s to 1670s for very important people. The engraving on the mother-of-pearl plate is exceptionally fine and perfectly readable despite its small size.
This perpetual calendar is by far the most beautiful example known for the type and is in an exceptional state of preservation, in its original condition.
Maker : nothing is known about this maker. The work is characteristic of a Parisian workshop of the middle of the 17th century according to the style and the engraving.
References : to the best of our knowledge, no perpetual calendar of this type is listed in public collections.
Overall dimensions: 5.4 x 4.0 x 1.0 cm
Materials: Tortoiseshell, mother of pearl and silver
Made in France circa 1650.
