what cannot be described, the agency of spirits. He saw that immateriality supplied no images, and that he could not show angels acting but by instruments of action; he therefore invested them with form and matter. This, being necessary, was there fore defensible; and he should have secured the consistency of his system, by keeping immateriality out of sight, and enticing his reader to drop it from his thoughts. But he has unhappily perplexed his poetry with his philosophy. His infernal and celestial powers are sometimes pure spirit, and sometimes animated body. When Satan walks with his lance upon the burning marle, he has a body; when, in his passage between hell and the new world, he is in danger of sinking in the vacuity, and is supported by a gust of rising vapours, he has a body; when he animates the toad, he seems to be mere spirit, that can penetrate matter at pleasure; when he starts up in his own shape, he has at least a determined form; and when he is brought before Gabriel, he has a spear and a shield, which he had the power of hiding in the toad, though the arms of the contending angels are evidently material.
