The refinements of the art were by Aristides of Thebes applied to the mind. The passions which tradition had organized for Timanthes, Aristides caught as they rose from the breast or escaped from the lips of Nature herself; his volume was man, his scene society: he drew the subtle discriminations of mind in every stage of life, the whispers, the simple cry of passion and its most complex accents. Such, as history informs us, was the suppliant whose voice you seemed to hear, such his sick man's half-extinguished eye and labouring breast, such Byblis expiring in the pangs of love, and above all, the half-slain mother shuddering lest the eager babe should suck the blood from her palsied nipple. This picture was probably at Thebes when Alexander sacked that town; what his feelings were when he saw it, we may guess from his sending it to Pella. Its expression, poised between the anguish of maternal affection and the pangs of death, gives to commiseration an image, which neither the infant piteously caressing his slain mother in the group of Epigonus,[23] nor the absorbed feature of the Niobe, nor the struggle of the Laocoon, excites. Timanthes had marked the limits that discriminate terror from the excess of horror; Aristides drew the line that separates it from disgust. His subject is one of those that touch the ambiguous line of a squeamish sense.--Taste and smell, as sources of tragic emotion, and in consequence of their power, commanding gesture, seem scarcely admissible in art or on the theatre, because their extremes are nearer allied to disgust, and loathsome or risible ideas, than to terror. The prophetic trance of Cassandra, who scents the prepared murder of Agamemnon at the threshold of the ominous hall; the desperate moan of Macbeth's queen on seeing the visionary spot still uneffaced infect her hand,--are images snatched from the lap of terror,--but soon would cease to be so, were the artist or the actress to inforce the dreadful hint with indiscreet expression or gesture. This, completely understood by Aristides, was as completely missed by his imitators, Raphael[24] in the _Morbetto_, and Poussin in his plague of the Philistines. In the group of Aristides, our sympathy is immediately interested by the mother, still alive, though mortally wounded, helpless, beautiful, and forgetting herself in the anguish for her child, whose situation still suffers hope to mingle with our fears; he is only approaching the nipple of the mother. In the group of Raphael, the mother dead of the plague, herself an object of apathy, becomes one of disgust, by the action of the man, who bending over her, at his utmost reach of arm, with one hand removes the child from the breast, whilst the other, applied to his nostrils, bars the effluvia of death. Our feelings alienated from the mother, come too late even for the child, who, by his languor, already betrays the mortal symptoms of the poison he imbibed at the parent corpse. It is curious to observe the
