Sirrush
In 1902, German archaeologist Robert Koldewey unearthed the fabled Ishtar Gate in the ruins of Babylon. The gateway was decorated with bas-reliefs depicting three animals, a lion, a wild oxen, and one mythical creature: the Sirrush.
The Sirrush [Mushrushu] was described as having a slender body covered with scales, a long slender scaly tail, and a long slim scaly neck bearing a serpent’s head … [from the mouth] a long forked tongue protrudes. There are flaps of skin attached to the back of the head, which is adorned (and armed) with a straight horn.
