Jean Miélot, also Jehan, (born Gueschard, Picardy, died 1472) was an author, translator, manuscript illuminator, scribe and priest, who served as secretary to Philip the Good, Duke of Burgundy from 1449 to Philip's death in 1467, and then to his son Charles the Bold. He also served as chaplain to Louis of Luxembourg, Count of St. Pol from 1468, after Philip's death. He was mainly employed in the production of de luxe illuminated manuscripts for Philip's library. He translated many works, both religious and secular, from Latin or Italian into French, as well as writing or compiling books himself, and composing verse. Between his own writings and his translations he produced some twenty-two works whilst working for Philip, which were widely disseminated, many being given printed editions in the years after his death, and influenced the development of French prose style.
Little is known of his early career. He was born at Gueschard, between Abbeville and Hesdin, in what is now the Somme department, but was then in Picardy, and from 1435 part of the Duchy of Burgundy. He was recruited by the Duke after he translated and adapted the Speculum Humanae Salvationis into French in 1448, and as well as his court salary he was made a canon of Saint Peter's in Lille in 1453, serving until his death in 1472, when he was buried in the church. He was probably not usually resident. As a priest and as an employee of the court he would have been exempt from guild regulations, which was probably an advantage to his career. He seems to have had lodgings in the palace, which are perhaps realistically shown in a miniature in Brussels, and also to have run a workshop of scribes in Lille. After the Feast of the Pheasant in 1454, an enthusiasm in the Court to revive the Crusades led to commissions to translate travel books about the Middle East.
