before him. Many miniatures went abroad, and foreign ones came to Italy. Gherardo, Attavanti, and others worked for Matthias Corvinus; and in the Burgundian Library at Brussels is preserved the mass-book painted for the king by the last-named artist in 1485, and brought to the Netherlands by Mary of Hungary, sister of Charles V. At Matthias’s death Lorenzo acquired several of the manuscripts, probably ordered at his own instigation, and some of which were still in hand. Lorenzo was deeply interested in the revival of mosaic. Vasari’s statement that Alesso Baldovinetti learned the long-forgotten principles of this art from a German pilgrim going to Rome must rest on its own merits; anyhow, the art was revived in Lorenzo’s latter years. In 1482-83, Baldovinetti undertook to restore the mosaics in the Baptistery. About 1490, Gherardo di Giovanni and Domenico Ghirlandajo began for Lorenzo the mosaic decoration of the chapel in the choir of the cathedral, where stands the shrine of St. Zanobi. This work was never finished. The same year Domenico executed the pleasing mosaic picture of the ‘Annunciation,’ over the side-door of the church, towards the Via de’ Servi. Baldovinetti’s pupil Graffione, and Ghirlandajo’s brother David, took part in these works; the latter, who busied himself with the technicalities of glass-making at Montaione, in the Elsa valley—where there are potteries and glass-houses to this day—afterwards worked both in Florence and in the cathedrals of Siena and Orvieto.[222]
