The Directorium ad faciendum passagium transmarinum is an anonymous 24,000-word Latin treatise on crusading submitted to King Philip VI of France on 26 July 1330 or 1332. The treatise proposes the conquest of the Holy Land, the Byzantine Empire and Russia and their subjection to the Catholic Church; outlines how this might be achieved; and describes how the conquered territories could be administered.

Jean Miélot, also Jehan, 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.
