History of the world
Whether in prehistoric or historic times, people always needed to be near reliable sources of potable water. Settlements developed on river banks as early as 3000 BCE in Mesopotamia, on the banks of Egypt's Nile River, in the Indus River valley, and along China's rivers. As farming developed, grain agriculture became more sophisticated and prompted a division of labour to store food between growing seasons. Labour divisions led to the rise of a leisured upper class and the development of cities, which provided the foundation for civilization. The growing complexity of human societies necessitated systems of accounting and writing.
History of Amiens
It was at Amiens that, for the first time, was defined one of the most ancient civilisations of humanity: The Acheulean. In 1853, "haches taillées" [carved axes], according to the term of the time, were collected in the old alluvium of the Somme at the level of the suburb of Saint-Acheul, east of the city. This discovery fascinated the greatest international experts of the time, Joseph Prestwich, Hugh Falconer, Charles Lyell and John Evans, who flocked to the site. In August 1859, Albert Gaudry discovered nine "carved axes" attesting, according to him, of the great antiquity of mankind. These discoveries marked the beginning of the great period of Saint-Acheul which lasted more than three-quarters of a century.
