The Corpus Christi Carol or Falcon Carol is a Middle or Early Modern English hymn (or carol), first written down by an apprentice grocer named Richard Hill between 1504 and 1536. The original writer of the carol remains anonymous. The earliest surviving record of the piece preserves only the lyrics and is untitled. It has survived in altered form in the folk tradition as the Christmas carol "Down In Yon Forest". The structure of the carol is six stanzas, each with rhyming couplets. The tense changes in the fourth stanza from past to present continuous. While a number of different interpretations have been offered over time, Eamon Duffy writes that "there can be no question whatever" that the carol's "strange cluster of images" are derived "directly from the cult of the Easter sepulchre, with its Crucifix, Host, and embroidered hangings, and the watchers kneeling around it day and night." One theory about the meaning of the carol is that it is concerned with the legend of the Holy Grail. In Arthurian traditions of the Grail story, the Fisher King is the knight who is the Grail's protector, and whose legs are perpetually wounded. When he is wounded his kingdom suffers and becomes a wasteland. This would explain the reference to "an orchard brown". The text may be an allegory in which the crucified is described as a wounded knight. The bleeding knight could be Christ who bleeds for the sins of humanity endlessly. Christ is most probably represented as a knight as he is battling sin and evil by his continual pain. The "orchard brown" to which the knight was conveyed becomes, in this reading, the "orchard" of wooden crosses that covered the hill of Golgotha/Calvary where Christ - along with many others - was crucified, while the "hall... hanged with purpill and pall" could be a representation of the tomb in which Christ was placed after Crucifixion. This allegorical interpretation would tie in with the seven stanzas possibly representing the Seven Deadly Sins. The maiden who is by the knight's side could be Mary. There is religious symbolism throughout the carol. The falcon may have several possible meanings. It may be that, as a bird of prey, it represents those who killed Christ and sent him to heaven. It may also represent a new beginning and freedom, which Christ gained on his death. The colours in the carol are
