But above all Mnemosyne, and her daughter Polyhymnia, must be propitiated by an art that would remember all things, Like Calchas in Homer, the pantomime must know all ‘that is, that was, that shall be’; nothing must escape his ever ready memory. Faithfully to represent his subject, adequately to express his own conceptions, to make plain all that might be obscure;—these are the first essentials for the pantomime, to whom no higher compliment could be paid than Thucydides’s tribute to Pericles, who, he says, ‘could not only conceive a wise policy, but render it intelligible to his hearers’; the intelligibility, in the present case, depending on clearness of gesticulation.
