This is a technical device for damping the vibrations of the mechanism!
In my last publication I have already touched upon the topic of the Cargo Cult. Then I offered my version of the purpose of the lingam. The prototype of the linga-yoni (lingam), in my opinion, was a part of some kind of rotary device with a crimper.
There were many different versions of the purpose of this "bowl" (disc), but none of them became the main one. I want to offer another original version of my own (briefly, discussed on one of the forums earlier), where the cult object of the Egyptians Disk Sabu dating from 3100 BC. e. is considered as a fake of a damper mechanism detail (damper flywheel) from a certain lost unit of the ancient civilization of the gods of Egypt.
In 1936, in the northern part of Sakkara (Egypt), a bowl-shaped vessel made of metasilt was discovered, dated to 3100 BC.
Gretarsson is his own work. Three-beam stone bowl ("Disc Sabu"), Sakkara, Ancient Egypt, first dynasty, diameter about 60 cm.
So, for those who have no idea what kind of detail this is …
In other words, this device is an anti-vibration device. Can't you feel the engine running in your car? This is the work of the anti-vibration device, including …

So, I suppose that the function of this part could be to reduce the amplitude of dangerous (critical) torsional vibrations in the operating modes of a hypothetical mechanism (say, it was mounted on the end of the shaft of an electric, gas turbine, etc. machine).
In short, this device could well have been an anti-vibrator (part of it is a damper flywheel) for a more stable operation of the mechanism. And the bent petals could play the role of the dampers themselves - in the event of critical resonant torsional vibrations, the “petals” slightly unbend and bend (under the action of centrifugal forces), i.e. could well change the nature of the vibration of the shaft of the hypothetical mechanism. Thus, the resonant torsional vibrations arising during the operation of the mechanism must be completely removed by the operation of this device.
This is how it looks schematically.

As for the "close" version as a fan / propeller, I will express my opinion. It seems to me that in this case this petal scheme is not functional. the shape of these petals does not allow directing the air / water flow parallel to the axis of rotation. Accordingly, the efficiency of such a "screw" will be negligible.
However, the shape of the petals of this "bowl" still resembles an aerodynamic one and, possibly, performs the same function as a fairing or a wing, first of all, with its lateral edge - during rotation it reduces the coefficient of aerodynamic air resistance, which in turn increases the torque moment. And at high shaft speeds - this is a very important circumstance!
Of course, this version is not ideal and has a number of comments … And the ancient master, making a copy in stone from a divine original, could have made a number of inaccuracies. But this version, it seems to me, is no worse than the official version of historians - according to which a similar subject is considered only as an oil lamp with a bizarre shape …
