3 thousand years ago, at the time of Ancient Greece and an era of blossoming of Egypt, on lands near the northern coast of the Black Sea there was a civilization Ancient Ukrov. It were the glorified workers which work was highly appreciated worldwide. Mentions of them are available in Euclid, Aristotle's works, persky chronicler Abu. They built houses, did house utensils, grew up animals. But that they appreciated most of all is a fat. All their life from infancy and to extreme old age was connected with this divine delicacy. It was the only civilization except Jews with monotheism - they worshipped to Great Saloyed. To this day archeologists and scientists are studied the majestic artifacts which have remained since then.
