And by the black bird might ye understand Holy Church, which sayeth I am black, but he is fair. And by the white bird might men understand the fiend, and I shall tell you how the swan is white without-forth, and black within: it is hypocrisy which is without yellow or pale, and seemeth without-forth the servants of Jesu Christ, but they be within so horrible of filth and sin, and beguile the world evil. Also when the fiend appeared to thee in likeness of a man of religion, and blamed thee that thou left thy brother for a lady, so led thee where thou seemed thy brother was slain, but he is yet alive; and all was for to put thee in error, and bring thee unto wanhope and lechery, for he knew thou were tender hearted, and all was for thou shouldst not find the blessed adventure of the Sangreal. And the third fowl betokeneth the strong battle against the fair ladies which were all devils. Also the dry tree and the white lily: the dry tree betokeneth thy brother Lionel, which is dry without virtue, and therefore many men ought to call him the rotten tree, and the worm-eaten tree, for he is a murderer and doth contrary to the order of knighthood.
