This epoch-making discovery, which is justly looked upon as the birth of modern painting, was made by the two brothers Van Eyck about the year 1410. The early accounts attribute the invention wholly to Jean, the younger of the two brothers, relating that on a certain occasion he had placed a painting on wood, which had cost him much time and labour, in the sun to dry when the heat of the sun caused it to crack. Seeing his work thus ruined at a blow Jean sought to find some substance that would obviate the necessity of drying his paintings in the sun and, after many experiments, discovered that linseed oil and nut oil were by far the most rapid in drying. He further found that the colours mixed better in oil than with the white of an egg or glue. They also had more body, a far richer lustre, were impermeable to water and--what was best of all--dried just as well in the shade as in the sun. Later scholarship is not inclined to give the entire credit for this discovery to Jean alone, however, and his elder brother Hubert is looked upon by some as the one to whom the glory is due. Probably it was the joint result of innumerable experiments made by both, each profiting by the mistakes and successes of the other--just as was the case with the Wright brothers in perfecting the greatest invention of our own times. There were, of course, other pioneers who contributed to the great discovery. The brothers were born at Maeseyck (Eyck-sur-Meuse) near Maestricht, and took the name of the village as their own in a way that was then very common. Literally they called themselves Hubert and Jean of Eyck. They first obtained service under the prince-bishop of Liége, and were illuminators of manuscripts and statues as well as painters. The increasing wealth and luxury of Flanders under the Dukes of Burgundy drew the two brothers to that country and they appear to have been in the employ of the Count of Charolais, afterwards the Duke Philip the Good, at about the date assigned by the early historians as that when the art of painting with oils was discovered. The Count was residing at that time in the Château des Comtes at Ghent with his young wife Michelle, sister of the Duke of Orleans. In 1419, when the news of the murder of John the Fearless, Duke of Burgundy, by the Duke of Orleans on the bridge of Montereau arrived at Ghent, Philip rushed into his wife's room crying, "Michelle, Michelle! Your brother has killed my father!" The shock of this terrible intelligence, and the subsequent suspicion of her husband that she knew of the plot, caused the poor little French princess to pine away and die two years later. As a tribute to her memory the guild of St. Luke was asked by the Duke to grant the freedom of the guild to her favourite painters, the two Van Eycks, which was done.
