Ancient Aliens in the Europe of Charlemagne

Historian brings evidence that the Frankish king Charlemagne was afraid of ships arriving from the sky. Thoughts on the UFOs fleet over the empire prevented him from sleep.
Ancient aliens

Quote from the newspaper
The Gauls were afraid that the sky will fall down on their heads, Charlemagne had no doubt in spite of his power, that aliens from other planets are a threat to his empire, these thoughts would not let him rest.
On this refers Jacques Vallée in his book “The Chronicles of visiting extraterrestrials.”
These uninvited guests, he says, had a human face.
They were called “sylphs”
They come from a country called “Mahonia”
They move to the wonderful airplanes, which the squadron took the shape of the loop.
Hundreds contemporaries King Charles met them. Especially in the Lyon region.

official information
Charlemagne (/ˈʃɑːrlᵻmeɪn/; 2 April 742/747/748 – 28 January 814), also known as Charles the Great (Latin: Carolus or Karolus Magnus) or Charles I, was King of the Franks. He united most of Western Europe during the early Middle Ages and laid the foundations for modern France and Germany. He took the Frankish throne in 768 and became King of Italy from 774. From 800 he became the first Holy Roman Emperor — the first recognized emperor in Western Europe since the fall of the Western Roman Empire three centuries earlier. While Charlemagne already ruled his kingdom without the help of the Pope, recognition from the pontiff granted him divine legitimacy in the eyes of his contemporaries

Jupiter Aurora

This view combines x-ray emissions from Jupiter’s auroras as seen by NASA’s Chandra X-ray Observatory with a visible light image of the gas planet taken at about the same time by the Hubble Space Telescope. While Jupiter’s auroras are particularly brilliant in ultraviolet light, they also shine in other types or frequencies of light, like x-rays.
DECEMBER 14, 2000: In this Hubble telescope picture, a curtain of glowing gas is wrapped around Jupiter’s north pole like a lasso. This curtain of light, called an aurora, is produced when high-energy electrons race along the planet’s magnetic field and into the upper atmosphere where they excite atmospheric gases, causing them to glow. The aurora resembles the same phenomenon that crowns Earth’s polar regions. But this Hubble image, taken in ultraviolet light, also shows the glowing “footprints” of three of Jupiter’s largest moons: Io, Ganymede, and Europa.

Ultraviolet images of Jupiter, taken by the Hubble Space Telescope, are assembled here into a movie sequence showing the planet’s brilliant, glowing auroras.
