Translator’s Preface

       In this Book, Morin explains the various classifications and subdivisions of the Signs and gives his opinion as to why some of them should be changed or rejected altogether. He gives what seems to him to be logical reasons for these features of the Zodiac. And as usual he quotes Holy Scripture from time to time. We should be aware that he was also primarily motivated by two things in astrology: (1) a dislike of anything that did not have a definite relationship to astronomy; and (2) a distrust of anything that seemed to him to have been originated by Arabian astrologers.

 

       Unfortunately, Morin's knowledge of the history of the World and the history of astrology, while consistent with what his 17th century contemporaries believed, was inferior to our knowledge today. Therefore, some of his “proofs” are no longer valid. And some of the subdivisions of the Zodiac that he discusses have fallen out of use and are hardly even known to modern astrologers. Still, his observations and comments are interesting, displaying as always his determination to put every facet of astrology on a logical basis. And unlike the majority of astrological writers, he does not simply enunciate a rule, but he also gives an explanation of why he believes it to be valid.

 

       In Chapter 1 Morin resumes his argument that the signs are the same both above and below the equator. And we are surprised to learn that he held a mistaken idea of how to calculate house cusps for places in the southern hemisphere. In the examples that he gives, he has simply taken the house cusps from the House Tables as if the Southern latitude was Northern latitude, which is of course incorrect. The proper procedure is to add 180 degrees to the RAMC and then copy the degree numbers of the cusps but reverse the Signs shown with them in the table. However, since he apparently only had two horoscopes of persons born in the southern hemisphere, this error did not affect his practice of astrology in Paris. It seems that he was so intent upon asserting that the Zodiacal Signs were not reversed below the equator, as some astrologers had suggested, that he was reluctant to change the procedure for using the House Tables, since that would imply that there was something different about astrology in the southern hemisphere.

 

       In order to make my translation of Morin's text easier to comprehend, I have italicized a number of technical terms. And I have broken up some of his long sentences into shorter ones. I have also added some words in parentheses, since he sometimes speaks rather shortly, especially towards the ends of sentences. And I have added some footnotes either to clarify the text or to provide my own comments.
