The temple, especially its crypts, contain several reliefs depicting statues of Harsomtus, sometimes syncretized with Ra, in the form of an upright snake, emerging from a lotus flower which is usually attached to a barge.

Norman Lockyer's passing reference to a colleague's humorous suggestion that electric lamps would explain the absence of lampblack deposits in the tombs has sometimes been forwarded as an argument supporting this interpretation (another explanation is the use of a system of mirrors).

[4] Proponents of this interpretation have also used a text stating that "high poles covered with copper plates were erected to break the storms[i] coming from on high" to argue this,[5][6] but Bolko Stern has written in detail explaining why the copper-covered tops of poles (which were lower than the associated pylons) do not relate to electricity or lightning, pointing out that no evidence of anything used to manipulate electricity had been found in Egypt and that this was a magical and not a technical installation.

[7] Archaeologist and debunker Kenneth Feder argued that if ancient Egyptians really had such advanced technology, some light bulb remains (glass shards, metal sockets, filaments...) should have been discovered during archaeological excavations.

By applying Occam's razor, he instead highlighted the feasibility of the aforementioned mirrors system, and that the ancient Egyptians knew that adding salt to torches minimized lampblack.
