In all that concerns movement, Verrocchio was a learner from Pollaiuolo, rather than an initiator, and he probably never attained his master’s proficiency. We have unfortunately but few terms for comparison, as the only paintings which can be with certainty ascribed to Verrocchio are not pictures of action. A drawing however like that of his angel, in the British Museum, which attempts as much movement as the Hercules by Pollaiuolo, in the same collection, is of obviously inferior quality. Yet in sculpture, along with works which are valuable as harbingers of Leonardo rather than for any intrinsic perfection, he created two such masterpieces of movement as the “Child with the Dolphin” in the courtyard of the Palazzo Vecchio, and the Colleoni monument at Venice—the latter sinning, if at all, by an over-exuberance of movement, by a step and swing too suggestive of drums and trumpets. But in landscape Verrocchio was a decided innovator. To understand what new elements he introduced, we must at this point carry out our determination to enquire into the source of our pleasure in landscape painting; or rather—to avoid a subject of vast extent for which this is not the place—of landscape painting as practised by the Florentines.
