The Great Bear. 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 copy in the Bodleian Library, end of 12th century CE. (Bodleian Library MS. Marsh 144).
Orion, also as a mirror image. Copy from the Bodleian Library, end of 12th century CE. (Bodleian Library MS. Marsh 144).
