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
Lantern, chamber and Gothic clocks
Domestic weight-driven clocks were made in southern Germany, Switzerland, Italy and Flanders from the fifteenth century. These 'Gothic' or chamber clocks have an open iron frame with corner posts, a verge escapement controlled by a foliot or balance wheel, and often an alarm or hour striking on a bell mounted above.
In England the lantern clock appeared around 1600: a brass posted-frame clock with a bell on top under decorative frets, hung on a hook or set on a wall bracket. After about 1658 many were converted to pendulum control, so originality of the escapement is a key question for any surviving example.
What to look for
- Iron (continental) or brass (English) posted frames with turned corner pillars and finials.
- A single hour hand — minute hands are rare before the pendulum era.
- Evidence of conversion: plugged holes, replaced escapement wheels or later pendulums.
- Fret designs and engraving on the dial centre, which help date English lantern clocks.
Dating clues
- Continental Gothic chamber clocks: c. 1450–1650.
- English lantern clocks: c. 1600–1720, with provincial examples later.
- Short 'bob' pendulum conversions after 1658; long pendulums with anchor escapement after c. 1670.
