The appearance of Halley's Comet in 1066 was recorded on the Bayeux Tapestry. The caption, ISTI MIRANT STELLA, was translated in a 1966 National Geographic article as "These men wonder at the star."

In the Bayeux tapestry we are shown two men gazing into the sky with the inscription Isti Mirant (These men wonder) then a fiery ball with a tail, with the word Stella (The star): and then Harold on a throne looking into the lower border of the tapestry where a ghostly fleet of ships is pictured.
