DE CLERCK, N. - Ioannes Aurelianus, Comes Engolismae, Avus Francis. I. Gall. Reg.

John of Orléans, Count of Angoulême and of Périgord (French: Jean d'Orléans, comte d'Angoulême, 26 June 1399 – 30 April 1467), was a younger son of Louis I, Duke of Orléans, and Valentina Visconti, and a grandson of Charles V of France. He was the younger brother of the noted poet, Charles, Duke of Orléans, and grandfather of Francis I of France.

John was taken hostage by the English in 1412, and not released until 1444. In 1415 he was joined by his older brother Charles, with whom he shared an interest in literature.[1] He had to sell part of his estates to pay for his ransom, but still collected many books. After that, he fought under the orders of his illegitimate half-brother.
