About the length of life technique:
I’m currently studying the subject and have stumbled upon a basic problem.
I’m uncertain as to which source should I try to master for the purpose of calculating length of life. It would also be useful for the purpose of conducting research on the subject, in the future.
From my impression so far, most contemporary sources use Porphyry’s method, and some use Vettius Valnes or Dorotheus. I do believe Lee Lehman considers Bonatti's method as the most reliable one. I don’t think that many regard Ptolemy’s method as superior and I’m not sure about the Arab sources, but I may be mistaken and that’s why I’d like to hear your input on the subject.
(-) Which Hyleg-Alcocoden algorithm do you use?
(-) Are you familiar with research which compares different methods for famous nativities?
