Thanks for the Plutarch reference and the Dendera link. That is a good explanation of the lunar cycle. Whilst Osiris is mentioned as the god in question, it seems that, like Horus, Osiris is everywhere. Perhaps, something has been lost in translation and this image represents another god, but the iconography is wonderful.
As regards the material for the Djed Pillar, taking into consideration the metals from Dynastic times, the suspects would be copper and/or electrum, poured or sheeted. The value of electrum would account for its disappearance, as well as the fact that in the intervening years, both Muslims and Christians, for religious beliefs peculiar to each religion, desecrated the icons of Egypt.
I have actually extrapolated the line from Abu Roash to Saqqara, but no pyramid or structure fits exactly, although Neferirkare is certainly very close. Saqqara was the burial field and one would expect to find tombs there. Giza, Zawyet el Aryan and Abu Roash served other purposes.
The line from Abu Roash to Zawyet el Aryan has a perfect alignment with the Serapeum.
