Ophidic folklore: the "Rainbow Serpent", the Nagas and the fairy Melusina

Mythical ancestors, cultural heroes, feral entities of the subtle world and supernatural brides: the topos of the ophidic-anthropomorphic mythical entities is widespread throughout the world, and affects both the European tradition (regarding which we will focus above all on the medieval tradition of the Fairy Melusina ), as well as extra-European traditions such as the Indian one of the Nagas, "serpent people" residing in the world below ours, that of the Hopi and that of the Australian aborigines.
