In viewing the poem as a medieval romance, many scholars see it as intertwining chivalric and courtly love laws under the English Order of the Garter. A slightly altered version of the Order's motto, "Honi soit qui mal y pense", or "Shamed be he who finds evil here," has been added, in a different hand, at the end of the poem. Some critics describe Gawain's peers wearing girdles of their own as linked to the origin of the Order of the Garter. However, in the parallel poem The Greene Knight, the lace is white, not green, and is considered the origin of the collar worn by the Knights of the Bath, not the Order of the Garter. Still, a possible connection to the Order is not beyond the realm of possibility. Christian interpretations The poem is in many ways deeply Christian, with frequent references to the fall of Adam and Eve and to Jesus Christ. Scholars have debated the depth of the Christian elements within the poem by looking at it in the context of the age in which it was written, coming up with varying views as to what represents a Christian element of the poem and what does not. For example, some critics compare Sir Gawain to the other three poems of the Gawain manuscript. Each has a heavily Christian theme, causing scholars to interpret Gawain similarly. Comparing it to the poem Cleanness (also known as Purity), for example, they see it as a story of the apocalyptic fall of a civilisation, in Gawain's case, Camelot. In this interpretation, Sir Gawain is like Noah, separated from his society and warned by the Green Knight (who is seen as God's representative) of the coming doom of Camelot. Gawain, judged worthy through his test, is spared the doom of the rest of Camelot. King Arthur and his knights, however, misunderstand Gawain's experience and wear garters themselves. In Cleanness the men who are saved are similarly helpless in warning their society of impending destruction. One of the key points stressed in this interpretation is that salvation is an individual experience difficult to communicate to outsiders. In his depiction of Camelot, the poet reveals a concern for his society, whose inevitable fall will bring about the ultimate destruction intended by God. Gawain was written around the time of the Black Death and Peasants' Revolt, events which convinced many people that their world
