Mysterious giant stone structure discovered by scientists in the middle East. Thousands of characters similar to famous drawings in the Nazca desert in Peru, stretching from Syria to Saudi Arabia. To see them whole and to assess the extent only from the air.
Ancient structures of stones, called geoglyphs, were first discovered thanks to the latest satellite mapping technology in Jordan.
According to David Kennedy from the University of Western Australia, in Jordan more than in the whole valley of Nazca. “Besides, they cover a much larger area and, apparently, much older,” the scientist said, noting that these geoglyphs at least 2 thousand years.
All buildings have a common design in the form of a circle with spokes, so they are called “wheels”. However, in the parts of the circles having a diameter of from 24 to 70 m, noticeably different.
The wheels are composed of diamond-shaped structures, small stone pyramids and randomly distributed low walls. Some buildings stand alone and others are grouped. In addition, in Saudi Arabia researchers have found a pentagonal design, as well as “wheels” with only two “spokes”. 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
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.
