Lacans, Lacanus, Lucanere de Buttelere, Lucans li Bouteillier, Lucant, Lucas the Botiller, Lukyn
He was the Duke of Cloucester, son of Duke Corneus and possibly brother of Bedivere, Sir Lucan appears to have been a good knight and sensible, and gentle in the best sense of the word. One of Arthur’s earliest knights, he may have been appointed butler at the same time Kay was named seneschal; at least, he appears in that post, serving with Kay and Griflet, at the feast given by Arthur in honor of his newly arrived allies Kings Ban and Bors.
Lucan fought valiantly in the battle of Bedegraine; we can probably assume that he also fought at Terrabil and on Humber bank. Through most of Malory’s work Lucan remains in the background, presumably carrying out his duties as butler. He does appear half a dozen times in the books of Tristram and those immediately following the Grail Adventures, cheifly jousting at tournaments. At least once during the books of Tristram Lucan shows up riding by and for adventure; he has now attained Round Table status. Outjousted and injured by Tristram, he is brought safely to the abbey of Ganis by Ywaine.
And when she came to the pavilion of King Arthur, there she alighted; and there met her a gentle knight, Sir Lucan the Butler, and said: Fair damosel, come ye from Sir Launcelot du Lake? Yea sir, she said, therefore I come hither to speak with my lord the king. Alas, said Sir Lucan, my lord Arthur would love Launcelot, but Sir Gawaine will not suffer him. ... I pray to God, damosel, ye may speed well, for all we that be about the king would Sir Launcelot did best of any knight living.
Now give me my spear, said Arthur unto Sir Lucan, for yonder I have espied the traitor that all this woe hath wrought. Sir, let him be, said Sir Lucan, for he is unhappy; and if ye pass this unhappy day ye shall be right well revenged upon him. Good lord, remember ye of your nights dream, and what the spirit of Sir Gawaine told you this night, yet God of his great goodness hath preserved you hitherto. Therefore, for God's sake, my lord, leave off by this, for blessed be God ye have won the field, for here we be three alive, and with Sir Mordred is none alive; and if ye leave off now this wicked day of destiny is past.
Arthur insisted on attacking Mordred, killing him but getting his own death wound in the process. Lucan and Bedivere got Arthur to a little chapel. Hearing people cry in the battlefield, the King sent Lucan to see what was going on. Lucan found robbers and pillagers stealing from the corpses.
When Sir Lucan understood this work, he came to the king as soon as he might, and told him all what he had heard and seen. Therefore by my rede, said Sir Lucan, it is best that we bring you to some town.
After this final battle at Camlann, Lucan tried to help Bedivere lift the King but, as he was so badly wounded, he fell dead. A variant of this is that Arthur embraced him but he was so badly wounded that the embrace killed him.
In Malory, Bedivere, the other survivor of the last battle, is called Lucan’s brother. I am not sure whether this means blood relationship, or brother in the sense that both were of the Round Table. In Vulgate VI, where Griflet and not Bedivere is the last knight left alive with Arthur, Lucan is nevertheless the next-to-the-last, and dies when Arthur embraces him.
Sir Lucan entered Arthurian literature early: Chrétien de Troyes casually mentions him as Lucan the cup-bearer.
