We have accounts of many different kinds of thunderbolts. Those which are dry do not burn objects, but dissipate them; while those which are moist do not burn, but blacken them. There is a third kind, which is called bright lightning, of a very wonderful nature, by which casks are emptied, without the vessels themselves being injured, or there being any other trace left of their operation. Gold, copper, and silver are melted, while the bags which contain them are not in the least burned, nor even the wax seal much defaced. Among the prognostics which took place at the time of Catiline’s conspiracy, Marcus Herennius, a magistrate of the borough of Pompeii, was struck by lightning when the sky was without clouds. CHAPTER VIII. NATURE OF THE EARTH. Next comes the earth, on which alone of all parts of nature we have bestowed the name that implies maternal veneration. It is appropriated to man as the heavens are to God. She receives us at our birth, nourishes us when born, and ever afterwards supports us; lastly, embracing us in her bosom when we are rejected by the rest of nature, she then covers us with especial tenderness; rendered sacred to us, inasmuch as she renders us sacred, bearing our monuments and titles, continuing our names, and extending our memory, in opposition to the shortness of life. In our anger we imprecate her on those who are now no more, as if we were ignorant that she is the only being who can never be angry with man. The water passes into showers, is concreted into hail, swells into rivers, is precipitated in torrents; the air is condensed into clouds, rages in squalls; but kind, mild, and indulgent earth, always ministering to the wants of mortals, how many things do we compel her to produce spontaneously! What odors and flowers, nutritive juices, forms and colors! With what good faith does she render back all that has been entrusted to her! It is the vital spirit which must bear the blame of producing noxious animals; for the earth is constrained to receive the seeds of them, and to support them when they are produced. The fault lies in the evil nature which generates them. The earth will no longer harbor a serpent after it has attacked any one, and thus she even demands punishment in the name of those who are indifferent about it themselves. She pours forth a profusion of medicinal plants, and is always producing something for the use of man.
