Hi, Martin

In a note by Zoller I found this to First Differentia:

On the First Differentia
?Look to the degree of the Ascendant of any nativity you wish and its ruler. Also, the rulers of the triplicity of the degree of the Ascendant, and the other angles and the rulers of their degrees and the luminaries and their rulers.?

?Indeed Aboali (Abu Ali al-Khayyat c.770-835) said that you look to the lord of the triplicity of the Sun, likewise Jupiter, Venus, and the planets diurnal and nocturnal, according as the nativity was diurnal or nocturnal. Look also to the Part of Fortune and its lord, similarly the lord of the conjunction or prevention which was before the nativity.?

But I don?t know on which page he found this? I have to look my books too..

Thanks. That may just be Zoller or Bonatti (on whom Zoller relies to a very great extent) superimposing the 'differentia' on Abu 'Ali's treatment of rearing, though. It would be good to see a more precise reference. (There is a more recent translation by Ben Dykes in Persian Nativities II.)
