Head IV

Head IV 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 Head IV rather than just read about it. In short: Head IV, sometimes subtitled Man with a Monkey, is a 1949 painting by Irish-born British artist Francis Bacon, one of series of works made in 1949 for his first one-man exhibition at the Hanover Gallery, in London. It measures 82 by 66 centimetres (32 in × 26 in) and is held in a private collection.

Key takeaways

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

Reference excerpt

Head IV, sometimes subtitled Man with a Monkey, is a 1949 painting by Irish-born British artist Francis Bacon, one of series of works made in 1949 for his first one-man exhibition at the Hanover Gallery, in London. It measures 82 by 66 centimetres (32 in × 26 in) and is held in a private collection. It was part of a series of six similar works from the late 1940s. Like Bacon's Head III and Head V, the painting is usually considered as intermediate between his better known Head VI. The painting was bought in 1949 by Tony Hubbard, heir to the Woolworth fortune. It entered the private collection of the New York broker Geoffrey Gates in 1963. It remains in a private collection.

Description The painting depicts the upper half of a male figure in a suit, in a rear quarter view facing away from the viewer, in a space shrouded with vertical bands interpreted as curtains. The figure is possibly looking in a mirror, where a simian face looks back. Like Head III, it is painted in dark tones of grey and black on a beige ground with white highlights, which in this case pick out the man's shirt collar, his neck, ear and temple. The placing of the two heads suggests the man is dissolving into the monkey, although the man is sometimes described as having a monkey on his shoulder; the low contrast between the elements have been likened to a cinematic dissolve. It may be based on a photograph. Bacon's six "Head" paintings were first exhibited at the Hanover Gallery in 1949, alongside four other important early works by Bacon: Three Studies for Figures at the Base of a Crucifixion, Figure in a landscape, Study from the Human Body and Study for Portrait (also known as Man in a Blue Box). Many are now held by major public collections.

Worked examples

Example 1 — a first encounter with Head IV

Start with the simplest possible case. Write down what Head IV 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 Head IV 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 Head IV 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 Head IV

In research: Head IV 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 Head IV 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: Head IV is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1949 paintings, Heads in the arts, Oil paintings on canvas, so understanding it makes those chapters shorter.
In everyday life: Look for Head IV 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.
