Aspects

1
Would anyone know if it was the opinion of Pingree that the aspects in Yavanajataka were just added there in a later edition? If so, is it possible that they instead represent a Seleucide-Sassanid tradition that has otherwise been lost? It's a little of a stretch to postulate direct and frequent connections between Egypt and India with a hostile realm in between (Ptolemaic Egypt and Seleucia were frequently at war, later replaced by Parthians). The yavanajataka also for example contains the beginnings of the ashtakavarga transit system, but I'm not aware of anything corresponding in Egyptian astrology.
