The House of Thoth
Thoth/ Djehuty here takes the form of an Ibis. He was god of wisdom, magic, writing and time. As god of the moon and ruler of the calendar, his role was to lighten the dark ways of the underworld. It was Thoth's great book of magic for which Setne Khamwas and the deceased Neneferkaptah gambled. One spell in this book gave a person the power to live on earth forever though they be dead and to; "see Re rising forth in heaven with all the gods in his company, and the moon in his form of shining."
House of Osiris -
The djed was a column, the symbol of strength and support. The hieroglyph also means stability or endurance. Perhaps it was symbolic of the tree from which Osiris’ coffin was made. It later became seen as the backbone of Osiris, hence a symbol of eternal life. In certain religious ceremonies when it was set upright it signified the rising of the soul to life after having overcome its enemies and the forces of death and decay.
The House of Neith
The image of the goddess Neith kneels before the symbol of the town of Abydos. In the hieroglyph she appears to be motioning toward the fetish of Abydos, which was also a symbol of Osiris. The town of Abydos was the traditional burial place of the dead god. It was also the centre of Osiris worship, and place of the major festivals of the dead.
The Missing House
This hieroglyph of a vulture was added by a later scribe and means ‘bald’ or missing.
The House of Ma’at
Ma'at is shown with the hieroglyph meaning "beautiful." She is goddess of truth, world order, justice, and righteousness. Her headband is the symbol of these attributes, and the ostrich plume is that feather against which the hearts of newly deceased were weighed before Osiris. The heart could not outweigh the feather if eternal life was to be achieved.
Ma’at supervises the Weighing of the Soul, portrayed in her dual-
First House of Tenet
We see on this square a hieroglyph that spells the name "tenet" followed by a sign meaning festival. The precise nature of this festival isn't clear. But if we consider the Senate board's aspects as a calendar, the sixth square is associated with the sixth day of the month (and the eight square, the Second House of Tenet, has the same sign),
The fact that these two ‘festival days’ surround the Tribunal day might be significant.
Court of the Thirty
This square is inscribed with the hieroglyph that means numeral 30. When Horus and Set did battle for supremacy over all Egypt, 30 Gods, known as the Divine Ennead, set up a kind of grand jury at Heliopolis to judge between them. In reflection of this Celestial court, the terrestrial judicial councils of Aegypt were similarly composed of thirty magistrates.
This is also a square of the Phoenix (royal and regulatory) priesthood when representing the Great Thirty Gods, and is the square that reminds us why, in order to become the 31st God amongst the 30 Houses, we should succeed at Senate.
Second House of Tenet
A reasonable assumption is that the major festival held in honour of Osiris in the city of Heliopolis is probably what is inferred by this square. (BD 1 S3, and other references).
House of Isis -
The dead person was instructed to set up the Djed and the Tiyt so that he or she might sail with the sun god in his celestial ship wherever he should go. (BD 100).
The Tiyt was a knotted belt that became a symbol of the goddess Isis. Because this amulet was normally made of red jasper, it specifically meant the magical blood of Isis, and was believed to protect Osiris (or the deceased) from harm in the Netjerworld (BD, 75, 156).
House of Edjo
We see in this House a goddess before a symbol for fire. Edjo (sometimes Uto or Wadjet) was the goddess of the delta town of Buto. She was the symbol of Lower Egypt and wears a recognisable red crown that indicates sovereignty over that ancient Kingdom of Lower Egypt. Sometimes she is depicted as a cobra.
Edjo often appears besides her related goddess, Nekhbet (square 11), the ruler of Upper Egypt. Both these goddess cobras are seen either side of Osiris' crown and on some mummified Kings. Both have an important role as protectors of the dead.
