Introduction
Zodiac remains the most controversial of all contributions of antiquity to the modern civilization. Often considered as the product of primitive imagination of the Babylonians, Zodiac has withstood the challenge of modern scientific world as the core of ancient occult wisdom and in one form or the other has been influencing the society astrologically, perhaps, in the most unscientific manner. Present work is not an effort to prove astrology as science but to bring to light the original rationale with which the zodiac or a model of time was conceived out of the celestial rhythms apparent on earth.

Zodiac in India – Rationale of the 21600 Minutes of Arc
In India Zodiac (mathematical abstraction of the ecliptic as a circle of 3600 and 21600’) is known by different names as K lacakra, R icakra, Jyoti cakra etc and explanations are available for each name. Looking at the astronomical works, we can see in S ryasiddh nta:

“Time is the destroyer of the worlds; another is the computed intervals. The latter is gross and minute or conceivable and inconceivable. Time in units of pr na is real and experienced and those like truti are imaginary. Six pr nas make a vin d , sixty of which is a n d “ Here we see the most fundamental Hindu conceptions of Time based on the duration of breath viz., Pr na during which the earth/celestial sphere was imagined to revolve through one minute of arc and thus the wheel of time was abstracted into 21600 minutes of arc or Pr na. It is said in G tik 6 of / (. i.e., the earth rotates one minute of arc in one breath of a man, of ryabhata too course of a Yogi. Pauli a siddh nta too aired the same notion as is evident from Alberuni2. It is apparent from the above that we have the conception of a human being of 21600 Pr na a day or 360 Pr na in 1N d or 900 Pr na in one hour – a being in tune with the sidereal rotation of earth. From sunrise to sunrise, Hindus observed the day and breath exercise or ‘pr n y ma’ had been a routine matter of the lives of ancient people as may be understood from the ancient literature. Against such a scenario, can it be accidental that we see the terminology of Yoga stra, all through out the Indian literature of astronomy and astrology – Jyotih stra? 1. Calendar is luni-solar and the same is true about the Yoga conception of breathing through two n d s ascribed to Moon and Sun viz., Id and Pi gal .
