PRISCARAXE
Mythology of Greece
Monstrous Humanoid Serpent
This is the name of a monstrous humanoid serpent said to be from the mythology of Greece. PRISCARAXE, according to a "discovered" fragment of ancient Greek script, was the mother of ALECTOR. The name and character was then incorporated by the Italian monk ANNIUS of VITERBO (Giovanni Nanni, c. 1432-1502) as ARAXA PRISCA, when he re-created a whole genealogy of GIANTS to justify the noble ancestry of the French nobility of the period. The was later supplemented by the humanist and poet LEMAIRE (1473-1524) and the name changed to ARAXA JUNIOR whom he compared as an ancestor, with MELUSINE.
