Summary
Description Al Sufi - Book of Fixed Stars - Ursa Major (The Great Bear) - Bodleian Library - Marsh 144.jpg |
English:
The Great Bear
as depicted in
Al Sufi's
c.
964
Book of Fixed Stars
. The familiar seven stars of the "
Big Dipper
", recorded by
Ptolemy
, are visible in the rump and tail, but notice they occur as a mirror-image of what we actually see because Al Sufi provided two images of each constellation, one as we see it in the night sky and one as seen here on a celestial globe. The image is from the
c.
1009 copy in the
Bodleian Library
, the oldest copy extant.
