in tempera in the life of Antonello da Messina. It is enough to note for the present that the efforts of the Florentines of the fifteenth century to substitute oil for other mediums were tentative and in a great measure unsuccessful; that a long time elapsed before tempera was abandoned altogether and that many pictures were ex ecuted partly in the old method and partly with oils. The perfected system of the Van Eycks was not dis covered in Italy, but introduced from the Netherlands, and came but slowly into common use. Though Andrea’s works in the choir of S.

In the foreground at each side kneel two canonized Benedictines. 2 One can still see that the figures were transferred from a
