Dr. Levente László – Quote on Facebook:“That said, the answer to the question, briefly, is that quadrant-based divisions appeared in the 5th century CE the latest, as a few nativities and inceptions of this era testify. In these horoscopes, quadrant-based divisions were used together with WSH. This practice continued both with later Byzantine astrology and—as far as I know, although I’m not a specialist of this area—Islamicate astrology until recent times, but for some reasons—and I suspect the relatively narrow scope of Arabic works translated to Latin in the 12th and 13th centuries should be accounted for this—the use of WSH wasn’t transmitted into Medieval European astrology“ – and „I’d add that to date, the subtleties and the rationale of this parallel usage are poorly understood since almost none of the relevant Islamicate and Byzantine horoscopes and theoretical material have been studied. Still, available evidence suggests that quadrant-based divisions tended to be employed in contexts where higher accuracy was expected, such as in annual methods for nativities, or where the astrologer wanted to make a case. It seems pretty likely to me that getting into cumbersome calculations required either clients willing to pay the price of exclusivity or specific demonstrative intentions from the astrologer’s part, so the choices were determined more by ease and purpose than theoretical considerations. Still, of course, this opinion should be revised when more sources become accessible.“.
What is still the unresearchable Enigma – What did the practice in the 9th Century on Questions, Elections and Mundane look like – Which houses and if more than one system – How and why and with what distribution – was the bulk of delineation only with WSHes?
