The similarity of this to the horrible catastrophe of Arras, recorded by the chroniclers of the fifteenth century, excepting the grosser absurdities of the latter, is almost perfect. Valentinian and Valens, who seem to have emulated the atrocious fame of the Caesarean family, with their ministers, concealed, it is probable, under the disguise of a simulated credulity the real motives of revenge and cupidity. The Roman world, Christian and pagan, was subject to the prevailing fear. That portion of the globe, however, comprehended but a small part of the human race. The records of history are incomplete and imperfect; nor are they more confined in point of time than of extent. History is little more at any period than an imperfect account of the life of a few particular peoples. Necessarily limited almost entirely to an acquaintance with the history of that portion of the globe included in the 'Roman Empire,' we almost forget our profound ignorance of that vastly larger proportion of the earth's surface, the extra-Roman world, embracing then, as now, civilised as well as barbarous nations. The Chinese empire (the most extraordinary, perhaps, and whose antiquity far surpasses that of any known), comprehending within its limits two-thirds of the population of the globe; the refined and ingenious people of Hindustan, an immense population, in the East: in the Western hemisphere nations in existence whose remains excited the admiration of the Spanish invaders; the various savage tribes of the African continent; the nomad populations of Northern Asia and Europe; nearly all these more or less, on the testimony of past and present observation, experienced the tremendous fears of the vulgar demonism.[29] [29] It may be safely affirmed, according to a celebrated modern philosopher, that popular religions are really, in the conception of their more vulgar votaries, a species of demonism. 'Primus in orbe deos fecit timor,' or, in the fuller expression of a modern, 'Fear made the devils, and weak Hope the gods.'
