Sorry Nag

The poor, wretched packhorse which Gawaine appropriates from the ugly squire for Greoreas and then is forced to ride himself, reminds me so irresistibly of Don Quixote's Rosinante that I cannot help but wondering if some image of Gawaine sitting on this unbudgeable nag to meet Greoreas' nephew could conceivably have echoed its way down four centuries to tickle Cervantes' funny bone.
