|Four depictions of the djed pillar: first, the stand form of the djed pillar, representing Osiris reborn as an evergreen tree (see: Christmas tree); second, Osiris in mummified form as djed pillar, in semi-human form, holding a flagellum and shepherd’s crook; third, a human-like form, with sun disc on his head, holding the djed pillar above him, out of which Ra-Khepri, aka the morning sun, arises; forth, Ptah, supposedly, in the mummified form of Osiris, holding the was scepter and the ankh. |
In 1892, Flinders Petrie suggested that the djed was derived from a pillar with four superimposed capitals; or alternatively, a picture of four pillars one behind another, according to the Egyptian ideas of perspective. 
In c.1910s, Wallis Budge popularized the theory that the djed pillar was the backbone of Osiris. 
In 1925, W. Kristensen suggested that the djed with its four crenels was the four pillars of heaven. 
In 1935, H. Gauthier suggested that the djed was a column made of reeds used to support the roof of a predynastic building. 
In c.1993, Jacobus van Dijk suggested that it was representative of Shu (or Heh) holding the heavens.
