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.
