All these fascinating images come from the first half of a hybrid manuscript of medieval astronomy, this particular section being written in Caroline miniscule and illustrated on vellum (it seems) in c. 1000 AD.
We are told:
" The main text in the older part is the Latin translation by Germanicus (15 BC-19 AD) of the Greek Phaenomena by Aratus of Soli (c. 315-c. 240 BC), which describes the constellations. This is illustrated with a series of remarkable diagrams and coloured drawings reflecting the overlap between myth, astronomy and astrology at this period."I was absorbed with this extraordinary book for over an hour. As the early 19th century owner wrote inside the front cover, "Astronomy and very curious".
