Alexander the Great is probably the biggest "Superstar" that ever existed on planet Earth! It is a non mythical - but flesh and blood - figure that has been fascinating millions of people all over the world for entire millennia! Still, to the disappointment of the astrologers, never a horoscope of this brilliant personality has ever been found. And we are very sure that astrologers DID erect Alexander's chart (or at least studied the positions of his birth planets) because Alexander lived his whole (actually short) adult life in Mesopotamia, in the very cradle of astrology! When Alexander the Great invaded this area and conquered Mesopotamia astrology was already considered a millennial tradition, applied especially to the mesopotamian kings! So, how comes we have never retrieved some cuneiform tablet with Alexander's the Great horoscope on it? The fact is that there are hundreds of thousands of cuneiform tablets in various museums etc. and very few people able to read them! So, it will probably take centuries before we decipher all of them and possibly discover an original, mesopotamian reference to Alexander's horoscope....
I have been personally conducting a research on Alexander's the Great horoscope since the early '90's. And I finally came up with a plausible date and time for Alexander's birth (you may see my relative article here). I was suggesting in that article that he were a Leo, with a Leo Ascendant too! And then to my amazement, a few months ago, as I was reading a Byzantine astrologer's text of the 11th century (George Kamateros) I saw the next line (first in Greek and then in English):
"Ο δεύτερος δεκανός (του Λέοντος) γεννήσει Αλεξάνδρου του κτίστου και Μακέδονος υπήρχεν ωροσκόπος"
"The second decan of Leo was the Ascendant of Alexander's the Macedonian nativity"!
As far as I know, this is the first ever historical evidence on Alexander's the Great horoscope! Of course you might consider - with all good reason - not very reliable such a piece of information coming from a Byzantine astrologer born 13 whole centuries after Alexander. But George Kamateros has been otherwise a reliable source. And he has to be considered a very special source too, because Byzantine literature is somehow a continuation of the Hellenistic one. At least, Byzantines preserved the hellenistic literature (just think of the many CCAG astrological volumes). I have personally studied many Alexander's the Great forged horoscopes (Gadbury's and Argoli's been the most famous). But these horoscopes apart from the fact that they smell "forgery" they were created by people disconnected from the hellenistic civilization. Kamateros on the other hand had a direct access to illustrious hellenistic astrologers such as Ptolemy, Hephaestion, Maximus and Rhetorius (the last two been more Byzantine than hellenistic astrologers). Thus, I consider reliable this Kamateros' precious piece of information on Alexander's Ascendant.
Maybe the day is not very far away when we will stumble upon the original horoscope (maybe of a clay tablet form) of this unique, ultra-brilliant human being!
