Good evening,
I agree with
Ms Margherita and also use no parallels of declination in practice. (Also i do not use nodes of any kind as to include the nodes of one wandering star to the exclusion of the others would not be a coherent approach and the inclusion of all of them would be beyond my mental capabilities.) However, if Mr
John Worsdale in following Sig.
Placido di Titi made consistent, coherent use of them as part of his methods of primary directions, one can scarcely object. One can simply attempt to follow the author to understand his astrological system and how well it works within its own framework. For me personally, the forest of primary directions generated by Mr Worsdale's system is too thick.
Concerning
ecliptical latitude, not parallels of it,
Klaudios Ptolomaios stated that a conjunction should be recognised only when all the participating bodies have northern or southern ecliptical latitude. Here is the relevant text from
Tetrabiblos, Book I, Section 24, in the English translation by Professor
Frank Robbins, emphasis added:
24. "Of Applications and Separations and the Other Powers.
In general those which precede 127 are said to "apply" 128 to those which follow, and those that follow to "be separated" from those that precede, when the interval between them is not great. 129 Such a relation is taken to exist whether it happens by bodily conjunction 130 or through one of the traditional aspects, except that with respect to the bodily applications and separations of the heavenly bodies it is of use also to observe their latitudes, in order that only those passages may be accepted which are found to be on the same side of the ecliptic. 131 In the case of applications and separations by aspect, however, such a practice is superfluous, because all rays always fall and similarly converge from every direction upon the same point, that is, the centre of the earth. 132"
For example, in the geniture of Master
Joseph Kent, both
Moon and
Saturn have southern ecliptical latitude, 4? 53' and 1? 34' respectively, validating the separating conjunction. One could comment on the delineations of these latitudes but this would drift off topic.
Mr
J M Ashmand's translation with the footnote give us, however, a somewhat different understanding than the above translation:
"... except that, in the application and separation of the bodily conjunction, it is also essential to observe the actual latitudes of the bodies, in order to receive and consider only such a transit as may be made in the same parts of the zodiac. 3
3 On this, Whalley says that "the less the difference of latitude of the planets in conjunction, the more powerful will be the influence: for if two planets in conjunction have each considerable latitude of different denomination, the influence of such conjunction will be much lessened."
The original ancient Greek text is
HERE. Perhaps someone fluent in this language and in astrology will inform us concerning the translations.
Of course,
ecliptical latitude and
equatorial declination relate to different coordinate systems. Nevertheless, the celestial bodies do not change positions because one expresses them in various coordinates.
