Held and catalogued by Rijksmuseum (object number BK-17012), this is a mechanical clock, made in Lyon urn:rijksmuseum:thesaurus:RM0001.THESAU.6141, France, dated c.1603 - c.1628. The Atlas places it in the Early Modern Horology period (1600 – 1750) of its Clocks collection. Materials and techniques recorded by the source: silver (metal) bronze (metal) glass. Recorded dimensions: height 19.7 cm width 6.3 cm depth 6.0 cm. The record is illustrated with 1 photograph.

Assembled from the source record's structured fields. Dates and attributions are given as the source states them; where a field is missing the Atlas leaves it blank rather than estimating.

Catalogue description

Catalogue description from Rijksmuseum

As a rule, Atlas carries a celestial globe, a three-dimensional map of the stars. A timepiece can also represent the universe, showing the movement of the stars. To enhance the engraving on the dial and foot, the furrows of the lines were filled with niello, a rich black alloy of silver, copper and sulphur.

Historical context

Early Modern Horology (1600 – 1750)

Huygens' pendulum and balance spring transform accuracy; English makers develop the anchor and deadbeat escapements.

Huygens's pendulum (1656–57) improved clock accuracy from about a quarter of an hour to under a minute a day. The anchor escapement (c. 1670) and the long seconds pendulum created the longcase clock; London makers such as Fromanteel, Knibb, Tompion and Quare led European clockmaking, and French makers created the Boulle pendule.

Atlas type guide

Bracket, table and spring-driven clocks

Spring-driven clocks freed timekeeping from the hanging weight. The coiled mainspring, documented from the fifteenth century, made portable table clocks possible; to even out its declining force, makers used the fusee, a conical pulley connected to the barrel by a gut line or chain. Renaissance table clocks from Augsburg and Nuremberg — drum-shaped, square or tower-shaped in gilt brass — were luxury scientific objects, often with astronomical dials and alarms.

After the pendulum, English makers developed the bracket clock: a wooden case with a carrying handle, a short pendulum with a verge escapement, and often repeating work to sound the hours on demand at night. Later examples use the anchor escapement. In the nineteenth century, 'table clock' became a broad term for spring clocks of every nationality.

What to look for

  • A fusee in the movement (cone-shaped pulley) and the type of line — gut or chain.
  • Verge escapement with a short bob pendulum, often with a decoratively engraved backplate.
  • Repeat cords or buttons that make the clock strike again on demand.
  • Gilt-brass engraved cases and horizontal dials on Renaissance pieces.
  • Case shapes: inverted bell, bell top, break-arch, lancet or balloon.

Dating clues

  • Drum and tower table clocks: c. 1520–1650.
  • Ebony veneered English bracket clocks with verge escapements: c. 1670–1800.
  • Engraved backplates were usual on English clocks until c. 1800, then generally plain.
