Jan Van Eyck [c. 1395 - 1441], or Johannes de Eyck, was a Flemish painter, one of the finest artists of the 15th century and also known as the "father of oil painting". Though the use of oil-based painting predates Van Eyck by several centuries, Jan and his brother, Hubert, were the earliest to use it for panel painting and to create extraordinary effects through the mastery of glazes, wet-on-wet and other painterly techniques.
The earliest source on Van Eyck is a biography  by Bartolomeo Facio. He describes the painter as one of the best artists of the 15th century and an educated man grounded in the classics. The earliest official record of Van Eyck is as court painter for John of Bavaria in 1422. At the death of John, Van Eyck moved to the court of Duke Philip the Good of Burgundy. His primary surviving work from this time is in the Turin-Milan Hours, an extravagantly illuminated manuscript which contained not only a book of hours but a prayer-book and missal as well. By 1479 a section of the manuscript belonged to the House of Savoy who gave it to the National Library in Turin in 1720. That manuscript, along with Van Eyck's illuminations, were lost during a fire in 1904.
