MYTHOLOGY
In this region of sky the man always has been accustomed to notice a sexy, vigorous and strong creature : the Sumeri identified Tiamat, a being cited in the Enuma Elish, poem on the creation of the world, while the Hebrew recognized the Leviathan, beast cited in the salm 74. The Greek ones instead spoke of Idra, that it figured in the collective imaginary like a great enemy of Eracle; it was daughter, second some, of the monster Tifeo and Echidna, than in its turn she was a feminine monster like a gigantic viper, Echidna was moreover mother of Cerbero, of the Chimera and the dog Ortro , with which she subsequently generated the Sfinge and the idra, exactly. During its second hard work, the son of Zeus had to hunt the enormous mortal creature and to burn all the heads of the animal before being able to behead the central head, decreeing therefore the definitive defeat of the idra. In the enterprise took part also Lolao,its grandson, that prepared a greatest bonfire, burning half forest for killing the heads of the monster. Only with this strategy it was possible to pull down the mythical fair. An other myth leads back it to the history of close crow.
