Green Knight of the story turns him green. He tests Moses three times by doing seemingly evil acts, which are eventually revealed to be noble deeds to prevent greater evils or reveal great goods. Both the Arthurian Green Knight and Al-Khidr serve as teachers to holy and upright men (Gawain/Moses), who thrice tested their faith and obedience. It has been suggested that the character of the Green Knight may be a literary descendant of Al-Khidr, brought to Europe with the Crusaders and blended with Celtic and Arthurian imagery. The beheading game appears in a number of tales, the earliest being the Middle
Palamedes (Arthurian legend) The "Palamedes" exists in fragments and as part of the vast "Compilation" of Rusticiano da Pisa, and details the adventures of two generations of Arthurian heroes. Some stories reveal Palamedes' background: his father was a king of Babylon who is sent to Rome where he saves the life of the Emperor. He then travels to Britain where he rescues and befriends King Pellinore. Many tales also have Palamedes as the hunter of the Questing Beast, an abomination only the chosen can kill. The hunt is as frustrating and fruitless as the pursuit of Iseult, and in most versions remains uncompleted.
