The most significant feature of the tomb is the astronomical ceiling, the earliest found so far, although similar calendars have been found on coffins lids from the Ninth Dynasty. The star maps illustrated the 36 "decans"or stars, that rose at sunrise, at ten day intervals. When he exited the tomb through the false door, Senenmut could then match the star with the decan calendar to determine the date in the calendar.

The ceiling painting is only partially completed with the original sketches still visible.

Details of the false door and the star map sketches of Taueret the hippopotamus goddess who protected women in childbirth are shown below. So far, I have been unable to determine which "decan" Taueret represents.
