La Vision de l'âme de Guy de Thurno

Simon Marmion was a Flemish painter and illuminator who was born in Amiens, France, around 1425. He was trained in the workshop of his father, Jean Marmion, who was also a painter and illuminator. Simon Marmion later moved to Valenciennes where he worked for the Duke of Burgundy, Philip the Good. Marmion is best known for his illuminated manuscripts, which were highly prized at the Burgundian court. His style was influenced by the International Gothic style, which was characterised by its decorative richness and attention to detail. Marmion's illuminations are known for their delicate, intricate designs, vibrant colours and fine detail. In addition to his work as an illuminator, Marmion also painted altarpieces and portraits. His altarpieces often depicted scenes from the lives of saints, while his portraits were notable for their realism and attention to detail. Marmion died in 1489 in Valenciennes. His work had a significant influence on later Flemish painters, including Gerard David and Hans Memling. Today, many of his illuminated manuscripts and paintings can be found in museums and collections around the world.

David Aubert was a French writer and translator who lived and worked in the late Middle Ages. He is best known for his translations of historical works from Latin into French, as well as for his own original works, which include chronicles, romances and poetry. Born in Brussels around 1420, Aubert worked throughout his life as a scribe and courtier for various noble families. He was also a member of the Order of the Golden Fleece, a prestigious chivalric order founded by the Duke of Burgundy. Aubert's most famous work is his translation of the Latin chronicle of Jean Froissart, a 14th century chronicler who wrote extensively about the Hundred Years' War between England and France. Aubert's translation, known as the Chroniques de France et de Bretagne, was completed in 1468 and became one of the most widely read historical works in late medieval France. In addition to his translations, Aubert also wrote several original works, including the Histoire du noble et vaillant chevalier Jason and the Livre des faits de Jacques de Lalaing, a biography of a famous Flemish knight. Aubert died in 1479, leaving a legacy as one of the most important writers and translators of his time. His works are still studied and appreciated by scholars and readers today.
