A very common scene with a very uncommon depiction of Anubis.
I came across an image of the "weighing of the heart" ceremony from a beautifully painted and exceptionallly well preserved coffin of the Lady Tahat, a 21st Dynasty chantress in the temple of Amun at Karnak. The coffin is housed in the Michael C. Carlos Museum at Emory University in Atlanta ( http://carlos.emory.edu/COLLECTION/EGYPT/egypt01.html
The cropped scene shows Anubis in his usual role of weighing the deceased's heart against the feather of Ma'at with the epithet iry mxAt
(Keeper of the Balance). However, Anubis is wearing the pschent, regalia traditionally reserved for the King of Upper and Lower Egypt (namely Horus in the scene that follows).
In the lower picture of the full coffin width, you can barely make out the scene that follows as what appeares to be Horus before Osiris, but it may in fact again be Anubis. Horus would traditionally be presenting the deceased to Osiris, but instead the figure before Osiris is accompanied by Ammit as Thoth records the events (this image of Thoth can be seen in the cropped image of the Weighing of the Heart).
I have never seen Anubis depicted this way. Can anyone please explain why he would be shown with 'a' crown let alone it being the Double Crown! To my knowledge, there is no mention of Anubis ruling Egypt in its mythology.
Is it possible that Horus is not present in the Hall of Judgement on this coffin and Anubis is taking on a "double role" of Keeper of the Scales and Presenter of the Deceased to Osiris?
