|In religio-mythology, Judgment Hall (TR:10), aka “Hall of Maat” (Ѻ), is location the dead were said to go in the afterlife, escorted there first by Anubis, for the initial soul weighing, i.e. to have the deeds of their soul weighted (see: soul weight), measured by 42 acts (see: negative confessions), against the feather of truth, on the scale of Maat, in the presence of 42 nome gods and Osiris, the king of gods, who sits at the thrown, accompanied by the goddesses Isis and Nephthys; the weight of the soul is recorded by Thoth; if the soul is heavy with sin, the monster Ammut "devours" the soul, and it goes into a fiery lake; if the soul is righteous or "light" with sin, the dead is led by Horus into the presence of Osiris and allowed into the afterlife.|
In c.3100BC, during the formation of the Egyptian 1st dynasty, the model of one supreme god presiding or reigning over 42 nome gods, one god for each territory or nome (state) of Egyptian, solidified; the first pharaohs, e.g. were generally known by their so-called "Horus name", i.e. Horus in life, Osiris in the afterlife, or something to this affect.
The following is a depiction of the Judgment Hall, from the Papyrus of Ani (c.1250BC), from the British Museum (No. 10,470), sheet 3 and 4), as found as a fold-out diagram in the last page of Wallis Budge's The Gods of Egypt, Volume Two (1904), showing the scribe Ani and his wife entering the hall to have his soul weighed, judged, and if successful, to go into the company of Osiris, and supposedly the Egyptian paradise afterlife, aka the "field of reeds" (Ѻ) or Aaru (Ѻ), the precursor to Christian heaven, or if unsuccessful to have his soul be eaten by Ammit and thereafter to go into the lake of fire, or duat, depending, the precursor to Christian hell: 
|In c.1375, such as found in the Book of the Dead of the scribe Hunefer (Ѻ), Judgment Hall was artistically conceptualized (Ѻ) as follows:|
In c.300AD, the Egyptian "Judgment Hall" became rescripted, during the Roman recension, into the model of “judgment day”, as follows:
wherein Horus became Jesus and Osiris became god, who judged the sum of the rights and wrongs of the acts of the dead, therein determining if he would go to either heaven or hell.
