same sign. How Saturn comes to exert this chilling influence William is less certain. He has already denied the existence of the congealed waters above the firmament, so that he cannot accept the theory that Saturn is cold because of its proximity to them. He can only suggest that its great distance from us perhaps explains why it heats less than the other planets.[143] The good and evil influences of the planets also come out in the astrological interpretation of myth and fable. Thus Saturn is said to carry a scythe because one who carries a scythe does more execution in receding than in advancing. Jupiter is said in the fables to have ousted his father Saturn because the approach of the planet Jupiter increases the evil influence of Saturn. Jupiter is said to have begotten divers children in adultery because the conjunctions of that planet produce varied effects upon earth; and Venus is said to have had adulterous intercourse with Mars because the propinquity of the planet Venus to the planet Mars renders the former less benevolent. Mars is god of battle because the planet of that name produces heat and drought which in their turn engender animosity.[144] As the tides follow the phases of the moon, so, William believes, a universal flood or conflagration may be produced by the simultaneous elevation or depression of all the planets.[145] But he accepts comets as special signs of the future caused by the Creator’s will instead of attempting to give a natural explanation of the events which follow them.[146] This is perhaps because of their signifying human events. Thunder and lightning are discussed without mention of divination from them.[147] [Sidenote: Science and religion.]
