About Akhekhu / Akhekh
Travelers who learned of Akhekhu brought stories of this fabulous creature to Europe, where it developed a new legendary status similar to that of the European griffin. 
Akhekhu had a serpentine body with four legs.  In later accounts held in Europe, Akhekhu had the body of an antelope with the head of a bird and serpent-like characteristics.  Often he is depicted with three uraei around his head.
