Egypt has always been a country of mysteries, the mighty Nile, and its inundations, its trackless desert; tombs and temples; obelisks and pyramids, its gods: Ra, Osiris, Isis, Apis, Horus, Hathor. The ancient Egyptians were highly cultivated. The age of the Pyramid-builders was a brilliant one. They were constructed during the age of the kings and used a vast amount of human labor.The reign of Khufu or Cheops is marked by the building of the great pyramid. The pyramids were the tombs of kings, built in the necropolis of Memphis, ten miles above modern Cairo.Egyptologists have noted that the whole life of the Egyptians was spent in the contemplation of death; They firmly believed that as long as the body remained intact so was their immortality.
