Art, myth, ritual, and crafts like astrology, all derive from archetype. This post demonstrates the Senmut pseudo-astronomical ceiling as an example. Culture is sustained and standardised by subconscious expression. I did not design archetype, or this quirky cultural expression of archetypal structure. I merely identify and demonstrate this expression. Astronomical figures are not primarily zodiac figures, since they are not conventionalised. However their ranges of attributes, their sequence, and their relative positioning are highly standardised, forming a mindprint.
