But the attack was not physical.

This royal had been dead for 20 years.

The attack was historical, an act of 'damnatio memoriae,' the damnation of memory.

Somebody smashed the pharaoh's statues, took a chisel and attempted to erase the pharaoh's name and image from history.

Who was this pharaoh, and what was behind the attack?

Here's the key: the pharaoh, Hatshepsut, was a woman.

In the normal course of things, she should never have been pharaoh.

Although it was legal for a woman to be a monarch, it disturbed some essential Egyptian beliefs.

Firstly, the pharaoh was known as the living embodiment of the male god, Horus.

Secondly, disturbance to the tradition of rule by men was a serious challenge to 'Maat,' a word for "truth," expressing a belief in order and justice, vital to the Egyptians.

Hatshepsut had perhaps tried to adapt to this belief in the link between order and patriarchy through her titles.

She took the name Maatkare, and sometimes referred to herself as Hatshepsu, with a masculine word ending.

But apparently, these efforts didn't convince everyone, and perhaps someone erased Hatshepsut's image so that the world would forget the disturbance to Maat, and Egypt could be balanced again.

Hatshepsut, moreover, was not the legitimate heir to the throne, but a regent, a kind of stand-in co-monarch.

The Egyptian kingship traditionally passed from father to son.

It passed from Thutmose I to his son Thutmose II, Hatshepsut's husband.

It should have passed from Thutmose II directly to his son Thutmose III, but Thutmose III was a little boy when his father died.

Hatshepsut, the dead pharaoh's chief wife and widow, stepped in to help as her stepson's regent but ended up ruling beside him as a fully fledged pharaoh.

Perhaps Thutmose III was angry about this.

Perhaps he was the one who erased her images.

It's also possible that someone wanted to dishonor Hatshepsut because she was a bad pharaoh.

But the evidence suggests she was actually pretty good.

She competently fulfilled the traditional roles of the office.

She was a great builder.

Her mortuary temple, Djeser-Djeseru, was an architectural phenomenon at the time and is still admired today.

She enhanced the economy of Egypt, conducting a very successful trade mission to the distant land of Punt.

She had strong religious connections.

She even claimed to be the daughter of the state god, Amun.

And she had a successful military career, with a Nubian campaign, and claims she fought alongside her soldiers in battle.

Of course, we have to be careful when we assess the success of Hatshepsut's career, since most of the evidence was written by Hatshepsut herself.

She tells her own story in pictures and writing on the walls of her mortuary temple and the red chapel she built for Amun.

So who committed the crimes against Hatshepsut's memory?

The most popular suspect is her stepson, nephew and co-ruler, Thutmose III.

Did he do it out of anger because she stole his throne?

This is unlikely since the damage wasn't done until 20 years after Hatshepsut died.

That's a long time to hang onto anger and then act in a rage.

Maybe Thutmose III did it to make his own reign look stronger.

But it is most likely that he or someone else erased the images so that people would forget that a woman ever sat on Egypt's throne.

This gender anomaly was simply too much of a threat to Maat and had to be obliterated from history.

Happily, the ancient censors were not quite thorough enough.

Enough evidence survived for us to piece together what happened, so the story of this unique powerful woman can now be told.
