praise of genius is due to the writer of an epic poem, as it requires an assemblage of all the powers which are singly sufficient for other compositions. Poetry is the art of uniting pleasure with truth, by calling imagination to the help of reason. Epic poetry undertakes to teach the most important truths by the most pleasing precepts, and therefore relates some great event in the most affecting manner. History must supply the writer with the rudiments of narration, which he must improve and exalt by a nobler art, must animate by dramatic energy, and diversify by retrospection and anticipation; morality must teach him the exact bounds, and different shades of vice and virtue; from policy, and the practice of life, he has to learn the discriminations of character, and the tendency of the passions, either single or combined; and physiology must supply him with illustrations and images. To put these materials to poetical use, is required an imagination capable of painting nature, and realizing fiction. Nor is he yet a poet till he has attained the whole extension of his language, distinguished all the delicacies of phrase, and all the colours of words, and learned to adjust their different sounds to all the varieties of metrical modulation.
