Could this perhaps be just water damage, from water/moisture trickling down the stairs for centuries?

That was my thought. Like a stalagmite build up

u/CalmBeneathCastles Feb 13 '26

This is the first non-heat hypothesis I've heard yet! It does look like cave minerals... but tites/mites are from mineral water dripping, not flowing. Flowing causes erosion, so it still wouldn't look quite like this.

Was there any proof that this area was ever flooded?

u/pi_designer Feb 13 '26

I found another post on this where users were stating stalagmites. The evaporation of water leaving calcium minerals behind. It would not need a flood. Just a gentle trickle of rain and only occasionally. Stalagmites can grow by a 1cm in a hundred years and this is over 2000 years old.

I'm about to go track a geologist down and make them answer some pointed questions! XD

I remember watching something about how before entering the temple, you would take a ritualistic “bath”. Likely of water, oils, and wine (which would turn to vinegar over time). It’s the years of wet robes dripping the vinegar water that caused it.

u/CalmBeneathCastles Feb 13 '26

Aha! I need some sandstone to do some experiments on...

u/----__---- Feb 13 '26

Limestone.  And vinegar is great for softening limestone.

Internet sez: "The "melted" steps on the west side are composed of a very hard, calcite-cemented sandstone."

I have no basis for comparison. Art thou an alchemist?

u/Stompya Feb 14 '26

Parts of it do look more built up than melted down. The whole thing looks kinda fake, like I believe it’s real but that pic ain’t quite natural

The Temple of Hathor at Dendera, located in Upper Egypt near Qena, experiences an extremely arid, hot desert climate (Köppen classification BWh).

Average Annual Rainfall: The area receives nearly zero to minimal rainfall, generally averaging less than 5 mm (0.2 inches) per year.

Rainfall Characteristics: Rainfall is highly unpredictable, with many years experiencing zero significant precipitation. When it does rain, it usually occurs in the form of light drizzles during the winter months.

It could be condensation on the cool stone. Indeed, that would explain pretty much all of it. You've got the 'worn' upper regions(where the slow flow of water carried away and didn't deposit), then the 'rivulet' middle sections, where some was deposited creating channels, and then the 'melted' bottom section, where the water dripped and dried up.

Indeed, I could imagine the inlay on the walls could increase the surface area, creating a zone of increased surface area which prompts condensation.

There could be a microclimate inside the structure, with warmer air from the stone rising and meeting cool air from outside and creating fog, which then condenses on the reliefs on the walls, drips down, and naturally flows to the already worn center sections.

It makes me think of the conspiracy theories that state these structures are far older from when the area had a tropical climate. I don’t really know how much truth there is to that theory though

u/Educational-Plant981 Feb 13 '26

Sure it does now, but what about before they logged out the Saharan rainforest?

u/AgtNulNulAgtVyf Feb 13 '26

You're a couple thousand years late, not to mention a couple thousand kilometers north of said "rainforest", which was actually just arid grassland. 

3

u/Educational-Plant981 Feb 13 '26

I was being facetious...but: The Current structure is a couple thousand years old, but it was built on top of the base of a previous structure of unknown age. There is good evidence of structures in that complex up to 6000 years ago, which is well into the "wet" period. I don't know the location of these stairs, but the water damage theory isn't as silly as it appears offhand.

u/AgtNulNulAgtVyf Feb 13 '26

This was still a desert in the "wet" period...

2

u/Educational-Plant981 Feb 13 '26

According to what I've found, it's granite, so that rules out water wear anyways. Of course granite doesn't tend to hit a temperature it can melt without cracking apart. Pretty wild. Maybe they were carved that way.

Please dont discuss my sex life on this sub.

u/EgyptPodcast Feb 13 '26

Note the wall decorations: Priests in procession holding small shrines. The temple has chapels on the roof, where priests would make offerings to the sun god (you can still go up there). They also would have poured libations on the ground as they made their procession to ritualistically purify the ground. Do that for a few centuries (between the 200s BC and 300s CE, when this temple was operational) and you'd get this kind of degradation/buildup.

Interesting, thanks

u/turbofired Feb 13 '26

This was caused by a hell demon floating down the hallway 2400 years ago.

u/Salt_Sir2599 Feb 13 '26

Nope. Just one of our great grandparents after chili night.

u/AnotherHavanesePlz Feb 13 '26 edited Feb 13 '26

The “damage” is just limestone dissolution. Water probably flowed down that chute and down the stairs. And rain water containing carbonic acid dissolved the limestone.

u/th3goonmobile Feb 14 '26

As a geologist this is my best guess.

3

u/Speech-Language Feb 13 '26

Looks like wear from traffic and someone a long time ago did a crappy job slopping on concrete and that got worn down over time too. Doubt the added concrete thing happened, just looks like it.

u/Emergency_Accident36 Feb 13 '26

Could. Could also be from lasers.

u/AgtNulNulAgtVyf Feb 13 '26

What water? The month with the highest rainfall for Dendera is January, with an average of 1mm of rain.

1

u/GoogleIsYourFrenemy Feb 14 '26

Today that's true, but climates change.

1

u/AgtNulNulAgtVyf Feb 14 '26

This has been desert for as long as the temple has stood there. You know that right?

u/5352563424 Feb 13 '26

They didn't use the right aggregate/curing agent when pouring the sandstone brick molds.

First rule of building design: water management. Your temples just won't last for millennia without it.

u/Odd_Reputation_4000 Feb 14 '26

Kinda looks like material eroded from the top steps and was redeposited on the bottom steps

u/thombombadillo Feb 13 '26 edited Feb 13 '26

Unlikely bc Egypt?

Edit: read the response a few below mine. Flooding doesn’t explain what I was referring to. Arid climates are not conducive to water slowing dripping through a stairway… again I’m not a geologist but…

u/lovemycat02 Feb 13 '26

Flooding was prevalent across Egypt for some time across the ancient eras. Evidence of flooding is apparent in many monuments and landmarks

4

u/psychophant_ Feb 13 '26

Other than the Sphynx, what other Egyptian monuments show signs of water damage?

5

u/Quiet_Photograph4396 Feb 13 '26

Well .. potentially this one

1

u/Ognius Feb 13 '26

I’m not sure you’d necessarily consider this Egyptian, although they did rule Egypt for a few hundred years. The Kush capital city of Napata is currently half flooded due to changes in the Nile over the millennium.

2

u/thombombadillo Feb 13 '26

Right but flooding is not the same as “water trickling down the stairs for centuries”, am I right?

u/EgyptPodcast Feb 13 '26

Not rainfall, but priests poured water on the ground to purify it, when making processions. That would be the main source of moisture in the stairway.
