The ancient history of mankind

The oldest stories on Earth tell us that humanity originated in one place and settled on the planet after happy lost his ancestral home. Different cultures call it differently: Hellenistic biblical Paradise or Eden. Modern scientists arguing about where was the first center of civilization, from stretched filaments of consanguinity linking the most remote peoples. Called Central Africa, and even Asia. To The Extreme North. However, in the main, researchers agree that the culture of antiquity is similar to the flames, as if blown by the wind to different parts of the Earth from one fire.

The main part of time in history every civilization has focused its attention on the development of certain areas of culture. So, the Romans created the most perfect law, which formed the basis of modern law. None of the administrative apparatus in the world could not compete with the extensive bureaucratic hierarchy of China. For a long time, astronomical calculations of the Maya had no equal among the peoples of the Old world. The nomadic tribes of the great steppe has created an outstanding movement system, allowing in the shortest possible time to throw masses of people and livestock over long distances. No civilization has tried to cover all areas of life at once. But it was not always so. Continue reading


India can be considered the third time a great civilization appeared on Earth (after Egypt and Mesopotamia ). But I immediately had to amend this statement, because in reality it is possible that it is the most ancient of civilizations, its study has just begun. As you probably already understood that civilization begin in the mouths of great rivers. In this case the Indus river (and the river luni, which is now lost in the Sands, and in those days formed a very powerful mouth and fell into the Indian ocean). And not only the Indus and the luni. This area is called Punjab – five rivers, once flowed here, three major rivers, from which there would be little.

By the way, the Indus was called actually Sindhu, but the Persians, from whom we learned about the existence of India, are unable to pronounce “with” in the beginning and started calling it “Hindu”. Greeks, taking the word from the Persians, and did cut it down to Indus. Continue reading

Water, created by the slaves of Rome.

In the history of the development of water supply systems of Roman aqueducts have a special place. Their extant remains indicate not only the Majesty and power of Ancient Rome, but also about the ancient world to the highest level of development of engineering thought.

The largest city of the ancient (by modern estimates, in the period of the Empire its population was from 600 thousand to 2 million people), also located in the hills, could not have developed water supply system. In it there were 11 aqueducts. First is Appies, named in honour of directing this project censor, Appius Claudius, was built in 312 BC and had a length of over 16 kilometers. The second aqueduct, built 40 years later, had a length of 70 kilometers! Same size there was also a third, Marziev, water. The total length of the Roman aqueducts was 436 km, 55 km – bridge structures. They delivered to the city, famous for its fountains and baths (Terme), from 700 thousand to 1 million cubic meters of water per day (according to some estimates – up to 1.5 million cubic meters). Such a large consumption of water may seem prohibitive, but you need to keep in mind that the ancient Romans did not know of valves, and the water in the system flowed continuously, obespechivayut sewage.
