These are the steps at the Temple of Hathor at Dendera Temple. Thousands of years ago people would have walked up and down these stairs with their offerings to Hathor. Praying for whatever it was that they so desperately needed. Whether it was to make money from a new business venture or hoping that their next child is a boy or maybe praying for good conditions to grow crops.
Sometimes the Temple would be visited by the pharaoh. He would probably be praying for something entirely different. Good favour for his current conquest against his enemies would be a likely scenario.
Over the millennia the soft stone has developed a melted look. This was caused by hundreds of thousands if not millions of people eroding away the surface.
Prayer was essential to Ancient Egyptians.
