These images from the 12th century manuscript “Annales Laurissenses”
(Latin for “volumes” or “books” about “historical and religious” events)
depicts the Saxon siege of Sigiburg Castle, France, in the year 776.
The Crusaders had the medieval French completely surrounded
when the “flaming shields” suddenly appeared in the sky;
(the manuscript reports this as being over a church).
Assuming the French were being protected,
the Saxons fled in fear from the UFOs.
