I'm inclined to believe that although there was an exchange, in terms of the zodiac, the exchange was pretty much one way, from the greeks/hellenists to the indian astrologers.Therese Hamilton wrote:Paul wrote:When discussing the sidereal zodiac we can't leave India out of the equation for the simple reason that there was an obvious interchange of astrological concepts between early western writers and India. So if we pick up a standard text on Jyotish we find in the chapter devoted to signs of the zodiac:I'm not so interested in the jyotish, my interest would be the western sidereal signs.
There are claims of a vedic zodiac but the evidence appears to suggest that primarily the vedic astrologers concerned themselves with lunar mansions rather than a solar zodiac. An article by Dieter Koch goes into this in more detail and I can link you to it if you like.
In any event any crossover which would occur in zodiacal symbolism in the early hellenistic period would have filtered through to both zodiacs as it would have occurred prior to the separation we have now.
I disagree with this logic. There can be any number of sidereally defined zodiacs as noted by the differing ayanamsha's and the logic for their usage. Some use Spica, others use other fixed stars. I'm not sure why one particular fixed star should gain such prominence as to have the entire zodiac modelled after it, but this seems to be the approach that is taken as I understand it. It's a problem then of, at the very least, calculation. With competing theories as to the best way to calculate the sidereal zodiac, we have competing sidereal zodiacs and their supporters. This is pretty much the point you yourself make, however we could also argue for a non-equally defined zodiac, perhaps based more on the actual visible constellations for example. This would still be a sidereal zodiac, just not the same kind as is popular. In fact to my mind it would seem to make more sense to use the constellations than simply place exceptional prominence on one star, and then for the purposes of calculation just ignore every other star and every other constellation.Likewise if it's a valid construct, there can be only one sidereal zodiac.
But as I say, my interest is in the non-jyotish astrology. Let's make it simpler and just say the astrology practiced by modern western sidereal astrologers. I'm still looking for a good source for understanding the symbolism of the signs in the sidereal system so that I could see whether there are dramatic differences.
