From Heine’s Atta Troll to the most famous illustration,Wilde’s Salomé, passing by Flaubert, Gustave Moreau and Huysmans, the modern genealogy of Salome’s “fin-de-siècle” myth is well known. Although, its origin remains still wrapped in some mystery. To unveil the genesis of this myth, we must ascend to the medieval beast-fable Ysengrimus written in Latin, one of the earliest branches of the Roman de Renart which presented for the first time the kiss to the decapitated head. It’s also necessary to examine the essential role of the Mythologie allemande (1835) by Jacob Grimm, who discovered the manuscript of this Latin epic in 1814, and of Atta Troll, written at the beginning of the golden age for the Salome myth in France. An examination of the relation among theses founder texts will bring us a new interpretation of this myth and of the crossing of two ways, French and German, from the medieval myth to modern lectures.
