"Music" is in some respects the most beautiful group of all, though the principal figure can hardly compare with that of "Arithmetic." This again is strongly reminiscent of Perugino. With drooped eyelids the symbolic sister daintily plays a violin; of four beautiful _putti_, two hold back the splendid dark green curtain, and two play the flute at "Music's" feet. Two old men are grouped together with Tubal Cain, who, as in the Spanish Chapel, forges musical instruments and keeps time with his swinging hammer. On the left is a charming group of boys--one playing the harp, another singing, a third, in rich dark robe and a student's cap upon his square out-flowing locks, touches a lute. In the spontaneity and unity that runs through all these figures, the suggestion of music and the sense of pleasure in it is rendered as in few other paintings of the Renaissance. We almost hear the strain, soft, fresh, heart-stirring, given without exaggeration or self-consciousness, to which the little _putti_ above seem to lean and listen, and we feel little doubt that this, the most lovingly painted, the most homogeneous of all the scenes, was painted entirely, or almost entirely, by Pintoricchio himself. [Illustration: _Anderson photo_] [_Borgia Apartments, Vatican, Rome_ FIGURE REPRESENTING ARITHMETIC] "Astrology" is the most damaged of any. The principal figure, which has been badly restored, must at any time have been entirely unworthy of the Umbrian master. The four _putti_, holding wands tipped with heavenly bodies, are much heavier and less dainty than his children. The groups at the sides, in one of which is a figure intended for Ptolemy, have no connection with the presiding patroness. That on the left, which is far the best, has, however, some admirable figures, Umbrian in character, and due to a pupil of Pintoricchio, who was thoroughly imbued with his master's spirit, and probably working straight from his sketches--indeed, a careful comparison of the hair and drapery of the youth who stands foremost, with extended arm, and holds an astral globe in the other hand, and the kneeling saint in the "Assumption," of the Hall of Mysteries, may persuade us that Pintoricchio is himself responsible for this delightful figure.
