 A variety of explanations have been proposed for this split perspective , which has even been suggested by Frederick Hartt to have been a practical joke . <unk> in these questions of perspective is Vasari 's criticism of the horse 's raising both its right legs at the same time , which would likely topple the horse , if accomplished . However , it is clear from Uccello 's other works that he was not interested in using perspective simply for realism ; rather , Uccello " placed in an unnatural , fantastic overall atmosphere , the fruit of this painter 's complex and unique imagination " . This style has even been cited as an example of synthetic realism in line with the late Gothic movement .
