Falling of the Black Serpent by Anke Eissmann.
The Black Serpent was a standard of the Haradrim, and especially the token of a mighty warrior and leader of Men. It was described as a black serpent upon a field of red (or more precisely, scarlet).
At the Battle of the Pelennor Fields the great commander of the Haradrim was called the Black Serpent. He was slain by King Théoden of Rohan just before his death.
