Head I

Head I 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 I rather than just read about it. In short: Head I is a small oil and tempera on hardboard painting by the Irish-born British figurative artist Francis Bacon. Completed in 1948, it is the first in a series of six heads, the remainder of which were painted the following year in preparation for a November 1949 exhibition at the Hanover Gallery in London.

Key takeaways

  • Head I 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 I to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Head I from memory before moving on to harder problems.

Reference excerpt

Head I is a small oil and tempera on hardboard painting by the Irish-born British figurative artist Francis Bacon. Completed in 1948, it is the first in a series of six heads, the remainder of which were painted the following year in preparation for a November 1949 exhibition at the Hanover Gallery in London. Bacon began the Head series out of necessity; he was granted the 1949 exhibition at the Hayward a year in advance, but had not painted at all in 1947, and had only a few works he was happy with from 1948. Over time, the series became something quite apart from his initial idea; Head VI turned into the first of his many examinations of Velázquez's c. 1650 Portrait of Innocent X.

Description Like the others in the series, it shows a screaming figure alone in a room, and focuses on the open mouth. The work shows a skull which has disintegrated on itself and is largely a formless blob of flesh. The entire upper half has disappeared, leaving only the jaw, mouth and teeth and one ear still intact. It is the first of Bacon's paintings to feature gold background railings or bars; later to become a prominent feature of his 1950s work, especially in the papal portraits where they would often appear as enclosing or cages around the figures. It is not known what influences were behind the image; most likely they were multiple – press or war photography, and critic Denis Farr detects the influence of Matthias Grünewald. Bacon juxtaposes traditional elements of portraiture with loose, spontaneous brushwork. In some passages he has rubbed or brushed out (perhaps with a cloth) the paint, a technique art historian Armin Zweite describes as "productive vandalism". There are a number of ambiguous elements in the work. The hanging tassel rest just above the figure's right ear, giving the impression that it has hooked the head and is pulling it sideways. The gold railings suggest in the top right suggest the corner of a room, while those in the center background may be the headboard of a bed. The upper half is largely void of detail, while the lower portion, particularly the lower third has been heavily reworked, and consists of a blending of white, gray and black pigments. The use of heavy impasto gives the impression of animal skin; critic Robert Melville described the "color of wet, black snakes lightly powdered with dust". In 1951 Bacon said of his choice of colour and gloss; "One of the problems is to paint like Velázquez, but with the texture of a hippopotamus skin", and later "I had an idea in those days that textures should be very much thicker, and therefore the texture of, for instance a rhinoceros skin would help me to think about the texture of the human skin". Furthering this impression, the mouth and teeth resemble those of a howling fanged animal.

Worked examples

Example 1 — a first encounter with Head I

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

In research
Head I 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 I 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 I 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 I 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 Head I in simple terms?

Head I is a small oil and tempera on hardboard painting by the Irish-born British figurative artist Francis Bacon. Completed in 1948, it is the first in a series of six heads, the remainder of which were painted the following year in preparation for a November 1949 exhibition at the Hanover Gallery…

Why does Head I 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 Head I?

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.
