Waiting for a Marvel
"King Arthur held court at Camelot in Christmas season. On New Year's Day he kept his vow not to begin the feast on such a high day before he had seen a marvel. As he waited, a horseman came riding into the hall, a Green Knight on a green horse; even the knight's hair and skin were green."
- From the introduction of Sir Gawain & the Green Knight, edited by J.R.R. Tolkien and E.V. Gordon (1936).
