Different from the foregoing is another work dealing with four parts of judicial astrology which the manuscripts ascribe to Roger of Hereford. Its opening words[534] and the subjects of its four parts all differ from those of the other treatise. Its first part deals with “simple judgment”; its fourth part, with “the reason of judgment”; while its second and third parts instead of third and fourth, as in the foregoing treatise, deal with interrogations, now called _Cogitatio_, and elections.[535] I know of no manuscript where this second work is to be found complete; in fact, I am inclined to surmise that usually the manuscripts give only the first of its four parts.[536] It professes at the start to be a brief collection of rules of judicial astrology hitherto only to be found scattered through various works. Astrology is extolled as an art of incomparable excellence without which other branches of learning are fruitless. “They appear to a few through experiments; ... it gives most certain experiments.”[537] The first book treats of the properties of the signs and planets, of the twelve houses, and defines a long list of astrological terms such as _respectus_, _applicatio_, _separatio_, _periclitus_, _solitudo_, _allevatio_, _translatio_, _collatio_, _redditio_, _contradictio_, _impeditio_, _evasio_, _interruptio_, _compassio_, _renuntiatio_, and _receptio_.[538] Some tables are also given, in connection with one of which we are told that the longest hour at Hereford exceeds the shortest by eleven degrees and forty minutes.[539] [Sidenote: _Book of Three General Judgments._] To Roger is also ascribed a _Book of Three General Judgments of Astronomy, from which all others flow_, which sometimes is listed separately in the manuscripts and apparently is found alone as a distinct work,[540] but in other manuscripts[541] seems to be an integral part of the work of four parts which we have just described. Its three general judgments are: gaining honors and escaping evils; _intentio vel meditacio_, which, like the _cogitacio_ mentioned above, refers to interrogations; and _comparatio vel electio_ which of course is elections. Thus the second and third parts of this _Book of Three General Judgments_ deal with the same subjects as the second and third books of the work in four parts, which makes it difficult to distinguish them. I am inclined to think that in those manuscripts where the _Book of Three General Judgments_ seems an integral part of the work in four parts, we really have simply the first of the four parts, followed by the _Book of Three General Judgments_.[542] At any rate it seems clear that most of Roger’s astrological composition is on the theme of interrogations and elections. _Iudicia Herefordensis_,[543] found in more than one manuscript, may come from a fourth work of his or be portions of the foregoing works.
