Jan van Eyck was probably born around 1390 in or near Maaseik, although neither his exact birthplace nor his birth date is securely documented. Little is known about his early life or artistic training.
He is first securely documented in 1422, when he was working at The Hague for John of Bavaria, ruler of Holland. Records indicate that van Eyck already had assistants, suggesting that he was an established artist by this time.
After John of Bavaria died in 1425, van Eyck entered the service of Philip the Good, Duke of Burgundy. Philip appointed him court painter and varlet de chambre. Van Eyck remained closely associated with the Burgundian court for the rest of his life.
His service involved more than painting. Van Eyck undertook journeys on behalf of the duke, some of which were connected with diplomatic business.
In 1428 he traveled to Portugal as part of a Burgundian delegation negotiating Philip's marriage to Isabella of Portugal. Van Eyck painted a portrait of Isabella that was sent back to the duke.
By 1431 van Eyck had settled in Bruges. The city was an important center of international commerce, and his patrons included members of the Burgundian court, clergy, merchants, and foreign residents.
One of the defining achievements of his career was the completion of the great altarpiece for the church of Saint John in Ghent, now Saint Bavo's Cathedral. An inscription associated with the work states that Hubert van Eyck began the altarpiece and Jan completed it. The precise division of work between the brothers continues to be studied.
The Ghent Altarpiece was completed by 1432. Its many panels bring together biblical figures, Christian theology, liturgical imagery, landscape, portraiture, and extraordinary observations of the material world.
Van Eyck continued to produce both religious paintings and portraits during the 1430s. Several surviving works contain dates and inscriptions that provide unusually valuable evidence for his career.
His paintings became celebrated for their convincing representation of surfaces. Metal, jewels, glass, stone, wood, skin, hair, and fabric appear with remarkable differences of texture.
This achievement depended in part upon van Eyck's sophisticated handling of oil paint. Thin translucent layers allowed light and color to be built gradually. Although he did not invent oil painting, he brought the technique to an exceptional level of refinement.
Van Eyck was also interested in inscriptions and language. Latin appears prominently in several religious works, and his paintings sometimes incorporate Greek or Hebrew characters.
He enjoyed considerable prestige during his lifetime. Philip the Good valued him highly, and contemporary and near-contemporary writers praised his artistic accomplishments.
Jan van Eyck died in Bruges in 1441. His paintings profoundly influenced Netherlandish art, and his approach to light, texture, landscape, portraiture, and religious symbolism affected generations of European artists.
