Aglovale
Knight of the Round Table, brother of Percivale and son of King Pellinore.
Aglovale is a knight of the Round Table in Malory's Le Morte d'Arthur, brother of Sir Percivale and son of King Pellinore. He is attested across five chapters with 15 citations, appearing primarily as a companion and protector figure. Malory lists his full lineage: "Sir Aglovale, Sir Durnore, Sir Tor, that was begotten upon Aries, the cowherd's wife... and King Pellinore begat them all, first Sir Tor, Sir Aglovale, Sir Durnore, Sir Lamorak, the most noblest knight" (Le Morte d'Arthur, Book XIX, Ch. XI).
Aglovale's most developed episode concerns the murder of his squire. The squire, seeking lodging, identified himself as servant to "a good knight that is with King Arthur, his name is Sir Aglovale" (Le Morte d'Arthur, Book XI, Ch. XI), expecting this would earn him courtesy. Instead, the castle lord "commanded to slay him" precisely because of Aglovale's name -- "for Sir Aglovale slew my brother" (Le Morte d'Arthur, Book XI, Ch. XI). This past killing, mentioned only in passing, reveals Aglovale's reputation as both feared and dangerous.
The vengeance is swift. On finding the dead squire in a churchyard, Aglovale demanded to know what happened: "What is there that ye behold so fast?" (Le Morte d'Arthur, Book XI, Ch. XI). Learning the cause, he declared: "as for thy brother, I avow it I slew him, for he was a false knight and a betrayer of ladies and of good knights; and for the death of my squire thou shalt die" (Le Morte d'Arthur, Book XI, Ch. XI). He called Percivale to join him, and together they entered the castle on foot, where Aglovale fought and killed Sir Goodewin, unlacing his helm and striking off his head (Le Morte d'Arthur, Book XI, Ch. XI).
The brothers' relationship shows strain. Percivale "departed from me unkindly" (Le Morte d'Arthur, Book XI, Ch. XII), Aglovale later complained, suggesting the younger brother's departure was felt as abandonment. They had ridden together first "unto their mother that was a queen in those days" (Le Morte d'Arthur, Book XI, Ch. X), establishing the family bonds before the narrative separated them.
Aglovale also appears briefly in the Grail narrative, where Gawaine "met with Sir Aglovale and Sir Griflet, two knights of the Table Round" (Le Morte d'Arthur, Book XIII, Ch. XVI).
