In the anonymous poem Sir Gawain and the Green Knight, the character of Sir Gawain is portrayed as the imperfect hero. His flaws create interest and intrigue. Such qualities of imperfection cannot be found in the symbol of the pentangle, which he displays on his shield. This contrast between character and symbol is exposed a number of times throughout the poem allowing human qualities to emerge from Gawain’s knightly portrayal. The expectations the pentangle presents proves too much for Gawain as he falls victim to black magic, strays from God, is seduced by an adulterous woman, and ultimately breaks the chivalric code by lying to the Green Knight.
