0 relating to an area of the sky through which the sun, moon, and most of the planets appear to move, divided into twelve equal parts, each with a name and symbol, and each connected with an exact time of year:
A system of 12 equal zodiacal divisions did not exist until circa 450 BCE.
This pyramid of light is called the "zodiacal light" because it lines up along the constellations of the zodiac.
The symbols for all the planets are entered according to the zodiacal sign they occupied on this birth date.
The pole of the first of these - actually the middle sphere in the complete model - is perpendicular to a plane that bisects the zodiacal belt.
Not all possible zodiacal (or for that matter musical) ratios are accounted for.
To my knowledge, however, no correspondence seems ever to have been established between pitches (or modes, or intervals) and the zodiacal signs.
The twelve zodiacal signs are assigned half to the male and half to the female figure.
Nor did they always consider the potency of celestial influence to be contingent upon the zodiacal aspects of the planets alone.
