Description

A fine example of brass ans silver three-discs German perpetual calendar, late 17th century, but here with a unusual very small size of 3,5 cm diameter.

The usual examples made between 4,3 and 4,7 cm diameter. The present example is a very miniature nicely and fully engraved.

Each side has a rotating brass plate, one engraved in german with the days of the week, the zodiac signs and the german words “Immerwehrender callender” ; the other engraved with months and times of sunrise, length of night, and zodiac.

The example fully written in German are rarest than the latine examples. So a classic-type but in German and in a rare smaller miniature size.

For an approching example attributed to Johann Martin but measuring 4,3 cm, see the Kern collection, volume II, pages 324 and 518, number 94.

Despite some trace of uses at the engraving of brass plates (visible on the pictures) a fine working example.
