Placidus and converse directions 1 by Martin Gansten I had previously asked a question about converse directions in Morin and earlier. Now I need some help from a real expert on Placidus/Placido de Titi. (Mike Wackford, are you there?) I have read in many places that Placidus advocated converse directions in the 'modern' sense ? that is, what we might call prenatal primary directions, since they perfected in the hours before rather than after birth. But now, reading Placidus's own examples in the Cooper Primum Mobile, I can't find any instances of this. Rather, it seems to me that Placidus is using the term 'converse' in the older sense of 'against the order of the signs' (but still following the primary motion after birth). Am I missing something? Are there clear-cut instances of Placidus using or advocating 'prenatal' converse directions? An example to make my point clear: let the Sun be on the Asc and Saturn near the 12th cusp. About 100 minutes after birth (25? in RA across the meridian), the Sun will reach a point corresponding to the natal position of Saturn. About 112 minutes before birth (28? in RA across the meridian), Saturn occupied a point corresponding to the natal position of the Sun. The two directions between these two points therefore perfect at different times (ages 25 and 28, respectively). Older astrologers would call the former a converse direction (and not calculate the latter at all), whereas 19th and 20th century authors would call the former a direct direction and the latter a converse. And as far as I can see, Placidus seems to use the older approach. Any help with this would be most appreciated! Quote Thu Sep 25, 2008 7:21 pm
