    Description
    View of Hevelius’s observation terrace with a group of revellers in the background and three figures in the foreground. The terrace shows astronomers using brass sextants and other instruments to observe a comet, which can be seen at the left corner of the image. The three figures in the foreground represent Aristotle (left), Hevelius (centre, seated) and Johannes Kepler (right).

    Aristotle is shown holding a diagram of his theory on comets. The solar system is shown as a geocentric model with the Earth in the middle, comets are shown between the Earth and the Moon, with the planet Mercury included to reference the wider solar system. This demonstrates Aristotle’s belief that all comets originated between the Earth and the Moon.

    Kepler is seen demonstrating his theory on comets, that they travel through the solar system in straight lines. His diagram shows a heliocentric system with the tails of the comets facing away from the sun.

    Hevelius is seated in the centre of the scene, calmly explaining his comet theory to his astronomical predecessors. He is seen pointing at a diagram which shows a comet in parabolic orbit around the sun, having originated from one of the outer planets of the solar system.

    A celestial globe is shown in the foreground, amongst other astronomical instruments. Many of the figures visible in the background can be seen looking up at the stars or pointing towards the comet.
