The basic measure unit used during the fourth Dynasty was the cubit, equal to 52,5 cm ( really someone says the measure is equal to 52,35 cm: it’s not so important. We’ll assume the value of 52,5 cm).

It was used, with its submultiples as well, according to the Anglo-Saxon model. We find it divided in half and quarters.

Besides, one cubit was equal to seven palms, and a palm is like four fingers, particular measure still in use.

The result is that a palm is equal to 7,5 centimetres, as we can practically test and the finger 1,85 cm, but I found values, connected to construction detail measures, between 2,5 and 3,0 centimetres.

Because I don’t know the real value of that kind of measure, I suppose it could be a finger and a half, that means 2,8 cm.

It is possible to detect this “small” measure in few very important details inside the pyramid ( I guess to have the possibility to show you something about later on ).

I disagree with the explanation that the royal cubit was an extrapolation of the human forearm length.

In Turin Egyptian Museum, it is possible to see a golden coated wooden cubit, belonging to architect Kha ( XVIII Dynasty ), who lived some centuries later than the fourth Dynasty.

There are some pictures on it showing human elbows in three different positions: closed, perpendicular bent and open straight.

I suppose it had a trivalent use, allowing a comparison between three different units of measures, taking the place of, during the following centuries.

Perhaps, at architect Kha living time, the cubit was reduced almost to a forearm length, but if I argue about my body measures, I’m not sure that this comparison could be right for the royal cubit.

I’m 172 cm. tall, a good height for the Ancient Egypt people, and the length of my forearm, from the elbow to the finger end, is just 47 cm.

If we want to compare the cubit length to any human body measure, we may find a relationship to the knee height from the ground ( try if you like).

That is reasonable if you think about a full handed working man.

This short note about the unit of measure used at that age is just to show that everything was planned for a long time, because all the internal and external measures of the Great Pyramid are as normalized standard score: that means they are multiple of the basic unit by whole numbers.

The hypothesis of a global project, where any detail was planned first, to be realized later on, is logic at this time.

This argument is very important to me and my theory is based on that, even if it is quite different from the usual opinion of the specialists.

In fact the Ancient Egyptian experts are convinced that three architects at least had run, alternatively, the Great Pyramid construction, changing continuously the project of the rooms inside.

They may have good reasons to think this, but I’m sure they are wrong and I hope to prove it.

The second matter is that the entire project was planned by an unique mind, a genius, who gave us the most extraordinary work of the human history, not completely explained yet, if my theory is right.

I’d help to clear it up.
