In the small room which opens out of the Tribune, on the opposite side to these three Tuscan rooms, are two perfect little gems of more northern Italian painting. Mantegna's Madonna of the Quarries (1025), apart from its nobility of conception and grand austerity of sentiment, is a positive marvel of minute drawing with the point of the _pennello_. Every detail in the landscape, with the winding road up to the city on the hill, the field labourers in the meadow, the shepherds and travellers, on the left, and the stone-cutterss among the caverns on the right, preparing stone for the sculptors and architects of Florence and Rome, is elaborately rendered with exquisite delicacy and finish. It was painted at Rome in 1488, while Mantegna was working on his frescoes (now destroyed) for Pope Innocent VIII. in a chapel of the Vatican. The other is a little Madonna and Child with two Angels playing musical instruments, by Correggio (1002), a most exquisite little picture in an almost perfect state of preservation, formerly ascribed to Titian, but entirely characteristic of Correggio's earliest period when he was influenced by Mantegna and the Ferrarese. Beyond are the Dutch, Flemish, German, and French pictures which do not come into our present scope--though they include several excellent works as, notably, a little Madonna by Hans Memlinc and two Apostles by Albert Dürer. The cabinet of the gems contains some of the treasures left by the Medicean Grand Dukes, including work by Cellini and Giovanni da Bologna. SCUOLA VENETA.
