"As many of us know, Placido Titi did use his own calculation of Part of Fortune, which he took from Adriano Negusanzio “nobleman from Fano, very expert both in the astrological doctrine according the true doctrine of Ptolemy, and in natural science and in the other secrets of nature… “
In his Canon de Parte Fortunae, Placido explains which is the true method and gives an example, showing the goodness of the method with the help of directions."
"Pars Fortunae is a part of the astrological tool-kit that is amply explained in all elementary introductions in Astrology and everybody is aware that it is derived from the positions of the Sun, Moon and the Ascendant. But apart from that, all manuals maintain a stony silence about the logic, or the historical background behind it.
The Arabic parts (and Bonatti mentions about 100 of them) are in fact Egyptian in origin. They are numerological or arithmetical fictions and they have no physical basis, but are fictitious points on the ecliptic.
