The term "astronomical diagram" is used on this site to describe a particular type of ancient Egyptian decoration, found on temple and tomb ceilings and on the outer surface of water clocks. A key feature of astronomical diagrams is the inclusion of decans.  Diagrams may or may not contain other elements, such as diagonal star tables, Ramesside star clock tables, and transit star clock tables, which are or will be described in detail in this database. Each astronomical diagram is unique, with variations found even when one diagram is a direct copy of another.

The extant diagrams fall into two groups, which in this database we will refer to as "astronomical representations" and "astronomical processions", with astronomical representations being the older and more long-lived variety.  The rationale and definitions for this classification system is contained in Symons (2015b).  The colours and letter codes in the tables are used in the schematic drawings of the more complete astronomical representations.  Areas of damage will be indicated by grey shading.

Features of Astronomical Representations

The distinctive features of astronomical representations are the inclusion of all the following elements:

C Circumpolar group of constellations Figures including a bovine foreleg (sometimes represented as a complete ox), a mooring post, and a hippo. A selection of additional figures may also be present.
A Attendant circumpolar deities Two processions of anthropomorphic deities one to each side of the circumpolar group.
D Decans Representations of decan stars. Both ordinary and triangle decans are included, with the triangle decans separated from the ordinary decans by the intervention of the superior planets. The decans can be represented by one or more of the following elements:
    Decan names.
    Decanal stars: a number of star or dot symbols.
    Depictions of decanal constellations.
    Cluster numbers of some decanal constellations.
    The names of related decanal deities.
    Figures of the decanal deities.
    Personifications of the decans in human form (rare).
P Planets Representations of the superior planets Jupiter, Saturn, and (sometimes omitted) Mars as falcon-headed deities. The two inferior planets are depicted after the triangle decans: Mercury (usually represented by name alone, sometimes with an accompanying deity name) and Venus (usually represented by name, a figure, and a deity name).

One or more additional astronomical elements from the following lists may also be present on astronomical representations:

M Calendrical ("month") elements Civil months as text.
Lunar months as figures or circles and/or labels.
Ramesside star clock tables.
The orientations of the Foreleg throughout the year.
N The sky-goddess Nut The figure of the goddess may be included either as an enclosing border or as a central figure.
X Other elements A baboon sitting on a djed-pillar.
The Sun and Moon personified.
