The Van Eycks--Hubert, the elder brother, and Jan--were natives of Maesyck (Eyck-sur-Meuse), and are famous as being the artists to whose ingenuity the first invention of the art of painting in oils was for a long time ascribed. The probability is that although the practice of mixing oil with colours was employed for decorative purposes in Germany and elsewhere long before their time, they were the first to so improve it as to make it fully serviceable for figure-painting.[105] The art of oil painting reached higher perfection in many ways after their time; but there is no picture in the Gallery which shows better than this, one great capacity of oil painting--its combination, namely, of "imperishable firmness with exquisite delicacy" (_On the Old Road_, i. 141). The place of the Van Eycks in the development of early Flemish art has been described in the introduction to that School, but the suddenness and completeness of their mastery remains among the wonders of painting. "The first Italian Renaissance," says Fromentin, "has nothing comparable to this. And in the particular order of sentiments they expressed and of the subjects they chose, one must admit that neither any Lombard School, nor Tuscan, nor Venetian, produced anything that resembles the first outburst of the School of Bruges." The two brothers were granted the freedom of the profession by the Corporation of Painters of Ghent in 1421. In that year Jan left Hubert and took an appointment as painter to Count John of Bavaria at the Hague. In 1424 he returned to Bruges as painter to Philip, Duke of Burgundy, in whose service he remained to the end of his life. Like Rubens, the painter Jan van Eyck "amused himself with being ambassador." "He was frequently employed on missions of trust; and following the fortunes of a chief who was always in the saddle, he appears for a time to have been in ceaseless motion, receiving extra pay for secret services at Leyden, drawing his salary at Bruges, yet settled in a fixed abode at Lille. In 1428 he joined the embassy sent by Philip the Good to Lisbon to beg the hand of Isabella of Portugal. His portrait of the bride fixed the Duke's choice. After his return he settled finally at Bruges, where he married, and his wife bore him a daughter, known in after years as a nun in the convent of Maesyck. At the christening of this child the Duke was sponsor; and this was but one of the many distinctions by which Philip the Good rewarded his painter's merits" (Crowe). But never was there an artist less puffed up. "Jan van Eyck was here." "As I can, not as I would." Such signatures are the sign-marks of modesty. In 1426 his brother Hubert died, leaving the great
