"Constellations of the star sky"
In dark, moonless and cloudless night in the sky the set of stars is visible. It seems, difficultly to understand this majestic picture of the star sky about which our great compatriot M. V. Lomonosov (1711-1765) with inspiration wrote:
"The chasm of stars has opened is full,
To stars of number is not present, a chasm - A bottom ". br/>
Even more difficultly the problem is represented to count all visible stars in the sky. But difficult at first sight, it becomes quite easy if to apply correct ways of its decision. These ways were created not at once, and decades and centuries, and the first of them leave the roots in an extreme antiquity. At the beginning of a human society when for the first time there was a primitive manufacture, already it was necessary for nomad tribes to be guided at transitions from a place of a pas a place to find a way to former places of parking. At higher step of development of a human society, at agriculture occurrence, there was a necessity to conduct, at least and rough, the account of time for regulation of agricultural works.
What exit saw from the created position the ancient people which did not have at the order even the bare rudiments modern us of sciences? It is unique that was always before them, and is more true, over them, is a star sky on which the ancient people began gradually to learn to be guided by districts and to keep count of time. Practical necessity of studying of the star sky has led to origin of the science which have received subsequently in the Ancient Greece the name of astronomy, an event from two Greek words: астрон-a star and номос - the law. p> But the name at all does not serve as the proof of origin and development of this science only in the Ancient Greece. The astronomy has arisen and independently degree of its development, naturally developed literally at all people, but, was in direct dependence on a level of development of productive forces and culture of the people.
If someone made fascinating travel from Moscow to Yaroslavl on the Yaroslavl highway, that should pay attention of a pas rather a small number of turns on all its extent. The highway is almost rectilinear, and its turns are connected only with detour of ravines, marshy places or too abrupt hills. And after all the Yaroslavl highway is laid basically on the old road connecting Moscow with Yaroslavl.
Both cities - almost coevals. Moscow is mentioned in annals since 1147 though, judging by last archeological excavations in the Moscow Kremlin, it as settlement existed already in second half Х century Yaroslavl based in 1010 By the same time occurrence of the traveller of a path between two cities concerns also. What way possible to pave in those days surprisingly direct shortest way between two cities removed from each other? Yes only same to what not less direct road between Moscow and Vladimir - orientation on stars has been laid; other ways of orientation in those days was not.
But how it is possible to be guided on stars if them the great variety is visible to a pas the sky? It would Seem, easily to get confused in this abundance of stars. Here for this purpose also it was necessary to group, first of all, bright stars (which in the sky not so already much) in the figures well remembered by the contours. Such star figures - Combinations of stars, or constellations - have been allocated, and later to them have carried also weaker stars located around constellations. It is quite natural that the various people created the imagination different constellations and if it is casual contours of constellations and coincided, they were called differently. As sources of names of constellations myths about gods, legends on legendary heroes and the events connected with them, various animals and, at last, the instruments of production used by the people in an everyday life, as a rule, served.
So, known group of seven bright stars, reminding a ladle outline, ancient Greeks named.
The Big Dipper. If to this group of stars to attach the weak stars located near to a ladle at sufficient imagination it is possible to spend borders of this constellation so that they will remind outlines of any big animal (fig.1)

The Greek myth tells that nymph Kallisto has been transformed by jealous spouse Zevsa the Hero into a she-bear who was badgered on hunting by dogs by its own son Arkad (Volopas). Zevs has given Kallisto immortality, having placed it in the sky in the form of constellation of the Big Dipper. Near to the Big Dipper its persecutors - Volopas and Hounds Dogs (fig.2) are located also, but the constellation of Hounds of Dogs has appeared in the sky only in XVII century when the Ancient Greek myth has been added by companions of the hunter. In the Ancient Gre...
