This week’s featured comet: The Great Easter Comet of 1066.

The Great Easter Comet of 1066–also called “The Comet of the Conquest”–was actually Halley’s Comet, making one of its 76-year periodic appearances. And 1066, you’ll remember from history class, was the year of the Norman Conquest of England.

Legend says that the comet appeared at Easter time and shone for forty days, waxing and waning with the moon:

“Under its seven rays, that year, William the Conqueror felt inspired to fall upon England, while Harold, the Saxon, on the other hand, saw in the Comet a star of dread foreboding and of doom.”

The comet lit the Normans’ trip across the English Channel, and William pointed it out to his soldiers to stir their courage, saying it was a sign from heaven of their coming victory.

Sigebert of Brabant, a Belgian chronicler of the time, wrote of the comet: “Over the island of Britain was seen a star of a wonderful bigness, to the train of which hung a fiery sword not unlike a dragon’s tail; and out of the dragon’s mouth issued two vast rays, whereof one reached as far as France, and the other, divided into seven lesser rays, stretched away towards Ireland.”

After the Norman Conquest, the comet was immortalized in the Bayeux Tapestry, sewn by William’s wife, Queen Matilda, and her court. You can still see the tapestry in Bayeux, France. In one panel, King Harold of England is shown cowering on his throne while his people huddle together in fear, pointing at the comet. The Latin legend over the picture reads “Isti Mirant Stella”: They marvel at the star.

One result of the Norman Conquest (and of the comet, you could say) is that we now have many, many words of French origin in the English language, such as “conquest,” “origin,” and “language.”

Comets and Aerolites

“Comets and Aerolites,” from Reynolds’s Series of Astronomical Diagrams, by James Reynolds, 1847. An aerolite is a meteorite, specifically, a stony meteorite consisting of silicate materials.

The falling stars you see in a meteor shower are from the “dust trail” left by comets as they circle through the solar system.

Comet Lithographs, 1850s

“Comets.” One of nine wall hangings, all on astronomical themes, that were among many produced by the Working Men’s Educational Union in the 1850s. They were printed lithographically on cotton, probably to avoid paper duty. The hangings would have been used in lectures, held at various locations, to illustrate the latest advances in knowledge.

Texas Star Party

A piece in the New York Times recently about the annual gathering of astronomy buffs in Fort Davis, Tx., for the 34th Texas Star Party:

About 500 astronomers, pro and amateur, have come from around the world to view the stars from this small, dark town. Fort Davis provides a light-pollution-free environment that’s surprisingly rare in the U.S. today.

The Great Comet of 1910

Another find from Stephen Ellcock, a series of French postcards published to commemorate the appearance of The Great Comet of 1910.

An odd narrative in the cards: The Earth, Moon, and Sun are anxiously watching the approach of the comet. At first they welcome the comet, but then the comet strikes the Earth, getting one of its points embedded near Alaska. The Moon and the Sun pull the comet free, and it sails off, crying blood tears, while the Earth recovers with a bandage.
