Tricorne

Tricorne is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Tricorne rather than just read about it. In short: The tricorne or tricorn is a style of hat in a triangular shape, which became popular in Europe during the 18th century, falling out of style by the early 1800s. The word "tricorne" was not widely used until the mid-19th century.

Key takeaways

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

Reference excerpt

The tricorne or tricorn is a style of hat in a triangular shape, which became popular in Europe during the 18th century, falling out of style by the early 1800s. The word "tricorne" was not widely used until the mid-19th century. During the 18th century, hats of this general style were referred to as "cocked hats". At the peak of its popularity, the tricorne varied greatly in style and size, and was worn not only by the aristocracy, but also as common civilian dress, and as part of military and naval uniforms. Typically made from animal fiber, the more expensive being of beaver-hair felt and the less expensive of wool felt, the hat's most distinguishing characteristic was that three sides of the brim were turned up (cocked) and either pinned, laced, or buttoned in place to form a triangle around the crown. The style served two purposes: first, it allowed stylish gentlemen to show off the most current fashions of their wigs, and thus their social status; and secondly, the cocked hat, with its folded brim, was much smaller than other hats, and therefore could be more easily tucked under an arm when going inside a building, where social etiquette dictates that a gentleman should remove his hat. Tricornes with laced sides could have the laces loosened and the sides dropped down to provide better protection from the weather, sun, and rain. Tricornes had a rather broad brim, pinned up on either side of the head and at the back, producing a triangular shape. The hat was typically worn with one point facing forward, though it was not at all unusual for soldiers, who would often rest a rifle or musket on their right shoulder, to wear the tricorne pointed to the left to allow better clearance. The crown is low, unlike the steeple hats worn by the Puritans or the top hat of the 19th century. Tricornes ranged from the very simple and cheap to the extravagant, occasionally incorporating gold or silver lace trimming and feathers. In addition, military and naval versions usually bore a cockade or other national emblem at the front. This style of hat remains in use in several countries to the present day as an item of ceremonial dress.

History

The tricorne appeared as a result of the evolution of the broad-brim round Cavalier hat used by Spanish soldiers in Flanders during the 17th century. By pledging (binding) the brims, a triangular shape was obtained. This shape was favored by Spanish soldiers, as when standing at arms, their muskets could be held at their shoulders right or left without hitting the hat brim. War broke out between France and Spain in 1667 over the Spanish Netherlands, and during the subsequent struggle, its use spread to the French armies. The style was brought back to France, where its usage spread to the French population and the royal court of King Louis XIV, who made it fashionable throughout Europe. By the end of the 17th century, the tricorne was popular in both civilian fashion and in military uniforms. It remained one of the predominant styles of hat in Europe and European-influenced countries throughout the 18th century, e.g. in the United States the first five presidents, from George Washington to James Monroe, wore this style of hat according to the fashion of the 18th century. James Monroe earned the nickname "The Last Cocked Hat" because of this. The tricorne quickly declined in use at the end of the 18th century. It evolved into the bicorne, which was widely used by military officers in Europe from the 1790s until World War I, not completely fading out of style until World War II. For enlisted soldiers, the tricorne was replaced by the shako at the turn of the 19th century, which had become the new dominant style of military headgear from 1800 on. Also at the turn of the 19th century, as the fashionable hat for civilian men, the tricorne was overtaken by the top hat. In 1917, the Women's Royal Naval Service introduced a smaller, modernised version of the tricorne for female officers.

Modern usage and legacy

Tricornes survive today as part of the traditional dress of the Chelsea Pensioners (UK) and the Old Guard Fife and Drum Corps of the United States Army, and the distinctive hat of the Spanish Guardia Civil, called a tricornio in Spanish, originates from the tricorne. In the UK, a black feathered tricorne hat is part of the ceremonial dress of most Lord Mayors; at the annual Lord Mayor's Show in November, the newly elected Lord Mayor of the City of London can usually be seen enthusiastically waving his tricorne at the crowds. In the British Parliament until recently, both the Lord Chancellor and the Speaker of the House of Commons used to carry plain black tricornes as part of their formal dress each day when on duty; only on rare occasions was it worn (on top of the full bottomed wig): by the Lord Chancellor when acting as a Lord Commissioner of the Sovereign, and by the Speaker when rebuking a Member at the Bar of the House. During the Introduction Ceremony, new members of the House of Lords were required to doff (remove and replace) a tricorne hat three times before the Lord Chancellor; however, hats were removed from the ritual in 1998.

Worked examples

Example 1 — a first encounter with Tricorne

Start with the simplest possible case. Write down what Tricorne 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 Tricorne 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 Tricorne 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 Tricorne

In research
Tricorne 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 Tricorne 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
Tricorne is common in secondary-school and first-year university syllabi. It links to neighbouring topics 17th-century fashion, 18th-century fashion, 19th-century fashion, so understanding it makes those chapters shorter.
In everyday life
Look for Tricorne 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.

Frequently asked questions

What is Tricorne in simple terms?

The tricorne or tricorn is a style of hat in a triangular shape, which became popular in Europe during the 18th century, falling out of style by the early 1800s. The word "tricorne" was not widely used until the mid-19th century.

Why does Tricorne matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Tricorne?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
