For a thousand years, artists recorded comets as omens, and then as science

the gist

For centuries Europeans drew comets, meteors and meteorites in ways that reflected how they understood the sky. The Bayeux Tapestry, from the eleventh century, shows people staring at Halley's Comet. Later German and French manuscripts depicted comets as warnings of disaster, with painters drawing them as fearsome signs above towns. In the sixteenth and seventeenth centuries, astronomers began to treat comets as objects that moved through the heavens, and treatises gathered observations and sketches. By the nineteenth century, illustrators were showing comets alongside careful records of orbits, meteor showers and meteorite falls such as the 1866 event at Knyahinya in Ukraine. The images trace a shift from prophecy to observation. Comets were the same objects all along; what changed was the way people looked at them.

so what

The sequence shows how the meaning of a comet moved from omen to physical body, a change that led to modern astronomy. Many of these pictures were produced in the same decades that scientists were confirming that comets follow orbits. Looking at them is a way to see how observation gradually replaced superstition.

fun fact

The Bayeux Tapestry, made in the eleventh century, includes a depiction of Halley's Comet.
