Victorian (mostly) Artists of Arthurian Legend

The Pre-Raphaelites:

The Pre-Raphaelite Brotherhood (or PRB) was a 19th century group of rebellious young artists who, disillusioned with the artistic climate of their day, sought to rediscover the purity of art by creating an entirely new artistic style that drew upon the middle ages, the bible, classical mythology and nature for inspiration, emulating the work of the great Italian artists before Raphael (hence their name: pre-Raphaelite). The PRB only lasted for five or so years, but it served to inspire many other painters such as Lawrence Alma-Tadema and John William Waterhouse throughout the rest of the 19th century and into the early 20th century.  (

And when they came to the sword that the hand held, King Arthur took it up.
He rode his way with the Queen unto Joyous Gard
   Then the king ran towards Sir Mordred, crying, "Traitor, now is thy death day come."
   Then Sir Launcelot saw her visage, but he wept not greatly, but sighed.
