Michelangelo's style of design is that of a sculptor, Andrea's of a colourist, Lionardo's of a curious student, Raffaello's of a musician and improvisatore. These distinctions are not merely fanciful, nor based on what we know about the men in their careers. We feel similar distinctions in the case of all great draughtsmen. Titian's chalk-studies, Fra Bartolommeo's, so singularly akin to Andrea del Sarto's, Giorgione's pen-and-ink sketch for a Lucretia, are seen at once by their richness and blurred outlines to be the work of colourists. Signorelli's transcripts from the nude, remarkably similar to those of Michelangelo, reveal a sculptor rather than a painter. Botticelli, with all his Florentine precision, shows that, like Lionardo, he was a seeker and a visionary in his anxious feeling after curve and attitude. Mantegna seems to be graving steel or cutting into marble. It is easy to apply this analysis in succession to any draughtsman who has style. To do so would, however, be superfluous: we should only be enforcing what is a truism to all intelligent students of art--namely, that each individual stamps his own specific quality upon his handiwork; reveals even in the neutral region of design his innate preference for colour or pure form as a channel of expression; betrays the predominance of mental energy or sensuous charm, of scientific curiosity or plastic force, of passion or of tenderness, which controls his nature. This inevitable and unconscious revelation of the man in art-work strikes us as being singularly modern. We do not apprehend it to at all the same extent in the sculpture of the ancients, whether it be that our sympathies are too remote from Greek and Roman ways of feeling, or whether the ancients really conceived art more collectively in masses, less individually as persons.
