MS Cotton Nero A.x, and is possibly its direct source. In the story of Sir Gawain and the Green Knight, however, the return blow is to be delivered in exactly a year's time. Sir Gawain, on his last night at Sir Bertilak's castle in Sir Gawain and the Green Knight, having gone through much to locate the Green Chapel at which he must suffer this return stroke of the axe, is determined, in truly chivalrous style, to be "merrier than ever before." Likewise, Gologras, in The Knightly Tale of Gologras and Gawain, is determined to be seen to be relaxed and "mery" in his hall, even when things are going badly for him outside and his knights are failing to gain the upper hand. This show of composure in adversity becomes a measure of honour and chivalry for both protagonists. And the climax of both The Knightly Tale of Gologras and Gawain and Sir Gawain and the Green Knight involves reciprocity. In the one, Sir Gawain takes upon himself what he has given to Gologras, that is, the mantle of defeat. In the other, Sir Gawain receives what he has given to his opponent, that is, a stroke of the axe. And not only a stroke of the axe, but earlier, also, in Bertilak's castle, a game was played in which everything that Bertilak had gained in the forest was given to Sir Gawain, and everything that Sir Gawain had achieved in the castle was (supposed to be) given to his host. More reciprocity. Amis and Amiloun A 14th-century Middle English poem Amis and Amiloun, found in the famous Auchinleck Manuscript, tells a story that contains many elements and motifs that are ultimately derived from European folklore. Based upon a 12th-century Old French poem Amis et Amiles, it tells of a pair of unrelated young men who are so alike that nobody can tell them apart. They swear blood brotherhood together, a pledge that is put to the test when Amis has to fight a trial by combat over a crime of which he is guilty. He rides to Amiloun, who by now is married, and they exchange identities. Amis rides back to Amiloun's castle pretending to be its lord. Amiloun rides away to fight the single combat on Amis's behalf, able to swear that he is innocent of the crime. Mabinogion Tales from the Middle Welsh Mabinogion are found
