For some reason, which I failed to discover, the catalogue of the Cotton manuscripts in the British Museum, in describing “a philosophical treatise concerning the principles of nature, the power of celestial influences on minds and morals, and other matters,”[96] states that “the author seems to be Athelardus.” The treatise is perhaps of later date than Adelard of Bath, but as it would be equally difficult to connect it with any other of our authors, we will give some account of it now. It seems to be incomplete as it stands both at the beginning and end, but the main interest in the portion preserved to us is astrological. Authorities are cited such as Hermes Trismegistus, Theodosius, Ptolemy, Apollonius of Thebes, “Albateni,” and “Abumaxar.” Discussing the number of elements our author states that medical men speak of the four parts of the inferior world, fire, air, water, earth,[97] but that astrologers make the number of the elements twelve, adding the eight parts of the superior world.[98] Later our author argues further for astrological influence as against “the narrow medical man who thinks of no effects of things except those of inferior nature merely.”[99] Our author holds that forms come from above to matter here below, and discusses the influence of the sky on the generation of humans and metals, plants and animals, and connects seven colors and seven metals with the planets.[100] He furthermore, in all probability following Albumasar in this, asserts that the course of history may be foretold by means of astrology and that different religions go with different planets.[101] The Jews are under Saturn; the Arabs, under Venus and Mars, which explains the warlike and sensual character of their religion; the Christian Roman Empire, under the Sun and Jupiter. “Ancient writers argue” and “present experience proves”[102] that the Sun stands for honesty, liberality, and victory; Jupiter, for peace, equity, and humanity. The constant enmity between the Jews and Christians, and Moslems and Christians, is explained by the fact that neither Mars nor Saturn is ever in friendly relation with Jupiter. These three religions also observe the days of the week corresponding to their planets: the Christians, Sunday; the Moslems, Friday or Venus’s day; the Jews, Saturday. Our author also explains the worships of the Egyptians and Greeks by their relation to signs of the zodiac. [Sidenote: Authorities on spirits.]
