    The idea

    Medieval medicine also relied on rational explanations, primarily the Theory of the Four Humours and miasma theory. Developed by Hippocrates, the humoral theory posited that the body contained four liquids (blood, phlegm, black bile, yellow bile); illness occurred when these were unbalanced. Galen expanded this with his 'Theory of Opposites', suggesting treatments to restore balance, like using a cold remedy for a fever. Galen's continuing influence in England was immense because his design-focused ideas fitted Christian teachings, leading the Church to promote his texts. Additionally, the miasma theory explained disease as being caused by 'bad air' filled with harmful smells from decaying matter, prompting early public health efforts.

    What earns the marks

    • Define the Theory of the Four Humours (blood, phlegm, black bile, yellow bile) and the concept of imbalance causing disease.
    • Explain the miasma theory as the belief that disease was transmitted by bad air or foul smells.
    • Describe Galen's contribution, specifically the Theory of Opposites used to treat humoral imbalances.
    • Explain why Galen's influence continued in England, focusing on the Church's endorsement of his ideas.
    • Recognise that these 'rational' theories were logical based on the observations of the time, despite being scientifically incorrect.

    Common mistakes and how to put them right

    • Attributing the original Theory of the Four Humours to Galen.

      Put it right: State that Hippocrates created the Theory of the Four Humours, while Galen developed the Theory of Opposites.

    • Treating miasma as a supernatural belief.

      Put it right: Categorise miasma as a rational explanation, as it relied on physical observation of smells and dirt.

    • Stating Galen was English.

      Put it right: Clarify that Galen was a Roman physician whose texts had a continuing influence in medieval England.

    Exam tips

    • Use the term 'rational' to describe theories based on observation and logic, contrasting them with supernatural beliefs.
    • When explaining Galen's influence, always link it to the power of the Catholic Church and its control over education.
    • Be prepared to explain how the Theory of the Four Humours linked to the seasons and elements.
