[Footnote: _Thus when great Angelo_, l. 303. The origin of this propensity to imitation has not been deduced from any known principle; when any action presents itself to the view of a child, as of whetting a knife, or threading a needle; the parts of this action in respect of time, motion, figure, are imitated by parts of the retina of his eye; to perform this action therefore with his hands is easier to him than to invent any new action; because it consists in repeating with another set of fibres, viz. with the moving muscles, what he had just performed by some parts of the retina; just as in dancing we transfer the times of the motions from the actions of the auditory nerves to the muscles of the limbs. Imitation therefore consists of repetition, which is the easiest kind of animal action; as the ideas or motions become presently associated together; which adds to the facility of their production; as shown in Zoonomia, Vol. I. Sect. XXII. 2. It should be added, that as our ideas, when we perceive external objects, are believed to consist in the actions of the immediate organs of sense in consequence of the stimulus of those objects; so when we think of external objects, our ideas are believed to consist in the repetitions of the actions of the immediate organs of sense, excited by the other sensorial powers of volition, sensation, or association.] "The Muse of MIMICRY in every age With silent language charms the attentive stage; 320 The Monarch's stately step, and tragic pause, The Hero bleeding in his country's cause, O'er her fond child the dying Mother's tears, The Lover's ardor, and the Virgin's fears; The tittering Nymph, that tries her comic task, Bounds on the scene, and peeps behind her mask, The Punch and Harlequin, and graver throng, That shake the theatre with dance and song, With endless trains of Angers, Loves, and Mirths, Owe to the Muse of Mimicry their births. 330
