Notes

This is the earliest surviving astronomical diagram in Egypt.  It is not, however, the first or original source for all others:  the general layout and composition of astronomical representations was establish by the early Middle Kingdom at the latest.

The ceiling is painted, not carved, and the background is light not dark blue.  It differs from most other two-register representations by having both registers follow the same orientation (stacked) rather than being back-to-back.  The lunar month circles are an obvious and unique feature.

Decan List

The list gives an approximate layout for how the decans, deities, cluster labels (x-nwt Xt), and decanal figures (in bold) are arranged.  However, the only way of perceiving the complete layout and orthography of the labels is by consulting photographs, drawings, or the original.  For conventions and abbreviations, see below the table. 

This decan list is used as the archetype for a family of over twenty astronomical representations.  Neugebauer and Parker call the list "the Senmut list" and the astronomical representations which that this list "the Senmut family".  Characteristic features of the decan and planet list are:  the exclusion of the superior planet Mars (SP3), the order of the Sahu decans, and the omission of decan 34 rmn sAH.

The decan numbers and letters shown here are for the decan family AR1

SP = superior planet

IP = inferior planet

Grey shading = damage

< > = omitted but understood

{ } = included in error

The number of star symbols accompanying the decans is also omitted here, as it is often impossible to tell to which decan the symbols refer.  EAT3 deals with star symbols in some detail.
