Key takeaways

  • Lantern clock belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Lantern clock to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Lantern clock from memory before moving on to harder problems.

Reference excerpt

A lantern clock is a type of antique weight-driven wall clock, shaped like a lantern. They were the first type of clock widely used in private homes. They probably originated before 1500 but only became common after 1600. They became obsolete in the 19th century.

Origin of the name There are two theories of the origin of the name "lantern clock". One is that it refers to brass, the main metal of which English lantern clocks are made. Clocks made on the continent, first of iron with iron wheels, and then later with brass wheels. Later still, in France, Belgium and The Netherlands, clocks began to be made from brass. Brass alloys were then called latten, and it seems likely that brass clocks would have been called "latten clocks" (or "latten horloge" or "latten uhr" in the native languages) to distinguish them from iron clocks, and that "lantern" could be an English interpretation or corruption of latten. The other is that the name derived from the shape; the clock resembles a rectangular lantern of that period, and like a lantern was hung on the wall. In inventories of deceased clockmakers, lantern clocks are usually referred to as "house clocks", "chamber clocks" or simply "clocks", since in 17th century England they were almost the only type of domestic clocks that existed. It was only after a century had passed, when other types of domestic clocks began to be used in British houses, that more descriptive names for it appeared. Other names used for lantern clocks are "bedpost", "birdcage" or "Cromwellian" clocks. "Sheep's head clock" was a nickname term for a type of lantern clock that had an extremely large chapter ring covering almost the entire front.

Origin of lantern clocks The English lantern clock is closely related to lantern clocks that can be found on the European continent. A group of craftsmen from the Low Lands (Flanders) and France, of which some were clockmakers, had established themselves in London at the end of the 16th century. At the same time the middle classes in towns and cities of England began to prosper and the need arose for domestic clocks. Until that time clocks in English houses were confined to the nobility; ordinary people were dependent on sundials, or the tower clocks of local churches. It is generally accepted that the first lantern clocks in England were made by Frauncoy Nowe and Nicholas Vallin, two Huguenots who had fled from the Low Lands.

Style characteristics

Lantern clocks were made almost entirely of brass, whereas most earlier clocks had been constructed from iron and wood. Typical lantern clocks comprised a square case on ball or urn feet, a large circular dial (with a chapter ring extending beyond the width of the case on early examples), a single hour hand, and a large bell and finial. The clocks usually had ornate pierced fretwork on top of the frame. The main style characteristics of English lantern clocks are similar to its Continental relatives: a wall clock with square bottom and top plates surmounted by a large bell, four corner pillars, a series of vertical plates positioned behind each other and a 30-hour movement with one or more weights. At the start of the 17th century, the style gradually evolved to a standard to which all clockmakers more or less complied. The guild supervised the clockmakers, who were compelled to work within a prescribed method. Suppliers to the clockmakers' trade contributed to this general style as well. For example, the brass founders supplied stylistically identical clock posts to several clockmakers. In contrast to the Dutch variants, such as stool clocks, English lantern clocks were entirely made of metal (brass and steel). Lantern clocks were originally weight-driven: usually one weight for time keeping and a second for striking. A few later lantern-style clocks were constructed with spring mechanisms, and many surviving examples of the original weight-driven type have been converted to spring or pendulum mechanisms.

Guild system

In only a few decades, the lantern clock became very popular in London and from there its popularity spread to the entire country. This is evident from the large number of lantern clocks that still exist. Dozens of clockmakers produced great numbers of these clocks in the city of London during the 17th century. This huge productivity was the result of the high demand for this popular clock in combination with an effective guild system. In 1631 King Charles I granted a charter for a clockmaker guild in London: the Worshipful Company of Clockmakers, which exists to this day. Many of the well-known clockmakers from that era were freemen of this guild. Before a clockmaker could become a freeman, able to set up his own shop, he had to spend seven years as an apprentice learning the trade. This ensured independent clockmakers a plentiful supply of apprentices, who were also cheap labourers who helped to attain this high productivity. Many small companies were established in Lothbury in London that functioned as suppliers for the clockmakers. A clockmaker could benefit from the services of brass founders who supplied cast brass clock parts, dial plates, finials, pillars, frets etc., or employ engravers who would carry out the engraving of the dial plates and frets. The guild assured the quality of the products that left the clockmakers' workshops.

Influence of the Renaissance Style characteristics were copied from prints that were available for craftsmen. Under the influence of the Renaissance, prints with motives and patterns from the Classical antiquity found their way to the workshops. They served as examples for the clock pillars that were inspired by columns from Greek temples. During the 17th century the tulip became very popular to an extent of a real tulip mania. Prints with pictures of tulips were a rewarding subject for the adornment of the dial plates of lantern clocks. In the early 17th century, lantern clocks got their characteristic shape, which hardly changed during the 17th and halfway through the next century as a result of all this.

Worked examples

Example 1 — a first encounter with Lantern clock

Start with the simplest possible case. Write down what Lantern clock claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lantern clock before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lantern clock ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lantern clock

In research
Lantern clock appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Lantern clock in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Lantern clock is common in secondary-school and first-year university syllabi. It links to neighbouring topics Antiques, Clock designs, Time measurement systems, so understanding it makes those chapters shorter.
In everyday life
Look for Lantern clock outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
