This spate of archaeological discoveries gave birth to the constant risk of seeing all these cultural riches leaving Egyptian soil. Auguste-Édouard Mariette, who visited Saqqara in 1850, became aware of the need to create an institution in Egypt responsible for the exploration and conservation of the country's archaeological treasures. He established the Egyptian Antiquities Organisation (EAO) in 1859, and organised excavations at Memphis that revealed the first evidence of the great temple of Ptah, and uncovered the royal statues of the Old Kingdom.
