You didn't do any reading, did you? No, it was not all BS. They were observing the same stars and planets we observe to this day. Of course they weren't observing the "forces" any more than you can observe the "force" of gravity. As they observed the planets they also observed and recorded human behavior. Over time they noted predictable, repeatable behaviors during certain times of year. Their observations are largely responsible for the analog clocks we've been using, divided into twelve hours.
And what predictions did they make regarding PMS.
I specifically referred to our ability to predict it these days. I suspect they also came to know and predict certain behaviors each lunar month, IYKWIM.
" Of course they weren't observing the "forces" any more than you can observe the "force" of gravity."
But we can test the force of gravity. We can indirectly observe it. No such luck with astrology.
". As they observed the planets they also observed and recorded human behavior. Over time they noted predictable, repeatable behaviors during certain times of year."
No they didn't. There aren't predictable behaviors based on birth date. It was much more than physical cycles they were attempting to predict; they predicted, as they do today, all sorts of things about love and romance, fortune or misfortune in wealth, the rise and fall of kings. That was the nature of the predictions made. These are all nonsense.
"Their observations are largely responsible for the analog clocks we've been using, divided into twelve hours."
That has nothing to do with astrological aspects of their work.
"I specifically referred to our ability to predict it these days. I suspect they also came to know and predict certain behaviors each lunar month, IYKWIM."
But menstrual cycles occur at all different times of the month. And this has nothing to do with astrology. Women didn't have to go to an astrologer to know when they were going to menstruate. You are now making up the nature of the astrologer's predictions.
