Math still causes headaches, even today, when we live in the age of computers and calculations should be a piece of cake for everybody. Well… they aren’t, especially when it comes to more complicated mathematical operations. But we all know that there were and still are people who’ve got calculations under their thumb.

The most convincing example is found in the sanctuary in the temple of Abu Simbel.

Here, twice a year, each year, the faces of Pharaoh Ramses II and of the gods Amun and Ra are illuminated by the sun’s rays, while the face of Ptah, sitting next to the others, is always in the dark. Moreover, the two days of this phenomenon are the birthday of the pharaoh and the day he was crowned (October 22 and February 22).
