The Osirion, the Dendera zodiac and the granite boxes of the Serapeum – favourites of "lost technology" debates.
UnchartedX, Foerster and others point to the precision of the Serapeum boxes and the Osirion’s megalithic style as signs of an older, technologically advanced culture.
Egyptologists attribute the Serapeum boxes to the Late Period (26th Dynasty onward, with inscriptions), the Osirion to Seti I (c. 1290 BCE) and the Dendera zodiac to the Ptolemaic–Roman era.
We present both views respectfully and link to the original work so you can judge for yourself.
