Professor Haskins ascribes one or more astrological works to Roger of Hereford and lists a number of manuscripts with three different _Incipits_.[527] Some of these manuscripts I have examined. One at Paris has the _Titulus_, “In the name of God the pious and merciful, here opens the book of the division of astronomy and its four parts composed by the famous astrologer Roger of Hereford.”[528] Roger explains that the first part is general and concerned with such matters as “peoples, events, and states, changes of weather, famine, and mortality.” The second is special and deals with the fate of the individual from birth to life’s close. The third deals with interrogations and the fourth with elections. The first chapter of the first part is entitled, “Of the properties of the signs and planets in any country,” and opens with the statement that it has been proved by experience that the signs Aries and Jupiter have dominion in the land “baldac and babel and herach,” Libra and Saturn in the land of the Christians, Scorpion and Venus in the land of the Arabs, Capricorn and Mercury in India, Leo and Mars over the Turks, Aquarius and the Sun in Babylonia, Virgo and the Moon in Spain. The other five signs seem to be left without a country.[529] Chapter two tells how to find what sign dominates in any villa; three, of the powers of the planets in universal events; four, of the science of the annual significance of the planets; five, knowledge of rains for the four seasons; six, knowledge of winds in any villa;[530] nine, the twenty-eight mansions of the moon. After the tenth chapter distinguishing these mansions as dry and wet and temperate, the second part on nativities opens with the retrospective statement, “Now we have treated of the first part of this art, omitting what many astrologers have said without experience and without reason.”[531] After a dozen chapters on the significance of the twelve houses in nativities, the author again asserts that in his discussion of that subject he has said nothing except what learned men agree upon and experience has tested.[532] After devoting three chapters to the familiar astrological theme of the revolution of years, he takes up in the third and fourth books[533] interrogations according to the twelve houses and elections, which are made in two ways according as the nativity is or is not known. The invocation of God the pious and compassionate in the _Titulus_ and the list of countries and peoples in the first chapter have a Mohammedan and oriental flavor and suggest that the work is a translation.
