What tradition says
Virgo gives the Sun nothing in the way of dignity; Mercury, by contrast, holds both domicile and exaltation there according to Ptolemy, a unique case of a planet twice at home in a single sign.
The Sun, ruler of the faces, would therefore be the guest of a very powerful host. Depending on the school, the decan would have an ordinary ruler or the most powerful one possible.
Teucer of Babylon, a 1st-century astrologer whose texts circulated as far as Persia and then the Arab world, already described a figure and spheres of influence for each decan. His lists are among the sources of the medieval treatises that fixed the imagery of the decans.
