Covering the story of Spanish art from the point where he left it at the beginning of the fifteenth century in his third volume, Professor Post devotes the present fourth volume to a consideration of the Hispano-Flemish period, particularly in Castile and Leon, which began with the union of those two kingdoms under Ferdinand and Isabella toward the end of the fifteenth century. Like the earlier volumes, this is very fully illustrated, with reproductions of masterpieces selected after personal investigation and study in Spain. It will take its place beside its predecessors as a welcome continuation of what will undoubtedly come to be considered the definitive history of painting in the Iberian peninsula.
