S. faceth the Concavity of the Heavens'.
A total of 21 stars are named, and a number are labelled by orientation. Four stars in Orion are labelled and two are indicated by a dotted line slightly deviating from the meridian. Nine are indicated by their Bayer notation. A total of ten constellation names are included for example, Ursa Major & Great Bear, Little Dog and Lyra.
