Chitra

Chitra is the fourteenth nakshatra, spanning the Virgo-Libra boundary from 173 degrees 20 minutes to 186 degrees 40 minutes of the sidereal zodiac, and its star is the brilliant Spica. Its Vimshottari ruler is Mars, its presiding deity is Tvashtar (also called Vishwakarma), the divine architect and craftsman of the gods, and its symbol is a bright jewel or pearl. The name means bright or brilliant. Jyotisha reads Chitra through craftsmanship, design, and dazzling form, the shining thing skilfully made, and classes it as Rakshasa gana. Tvashtar's association makes it a mansion of the maker and the beautiful artifact. These are traditional interpretations laid over Spica, the first-magnitude star that Indian astronomy places at this point and that many ancient calendars used as a seasonal marker.

Chitra's padas run through Sagittarius, Capricorn, Aquarius and Pisces. Tvashtar, also identified with Vishwakarma in later texts, is credited in Vedic and Puranic literature with forging the weapons of the gods and shaping the forms of living beings, a double office as craftsman and as maker of bodies that gives Chitra's association with design and craftsmanship a cosmogonic weight beyond ordinary artisanship. Spica itself is a rotating ellipsoidal binary star system rather than a single star, too close and too fast an orbit to resolve visually, a modern astrophysical fact with no bearing on its ancient role as a harvest marker across Mesopotamian, Egyptian and Indian calendars alike, all of which independently used its heliacal rising or setting to fix agricultural dates.

The nakshatra is not the last cut. Each one is divided again into four padas, and most of what a jyotishi reads from a lunar position is read at that level rather than at the level of the nakshatra itself. Chitra runs from 173 degrees 20 minutes to 186 degrees 40 minutes of the sidereal circle, and its four padas are three degrees twenty minutes each: the first from 23 degrees 20 minutes of Virgo, the second from 26 degrees 40 minutes of Virgo, the third from 0 degrees 00 minutes of Libra and the fourth from 3 degrees 20 minutes of Libra. The Moon crosses a single pada in roughly six hours, so a birth an afternoon apart can fall in two of them.

The arithmetic hides a coincidence that is not one. Twenty seven nakshatras of four padas make one hundred and eight divisions of the zodiac, and the navamsha, the ninth-part chart that jyotisha treats as the most important of all the divisional charts, also cuts the circle into one hundred and eight. They are the same cut. A pada is a navamsha, and naming the pada names the navamsha sign without any further calculation. The four padas of Chitra fall in Leo, Virgo, Libra and Scorpio in that order.

Two cautions attach to those degrees. They are sidereal, measured from a fixed point among the stars rather than from the equinox, so they depend on the ayanamsha chosen to locate that point; the Lahiri, Raman and Krishnamurti values differ by up to about a degree, which is a fifth of a pada and enough to move a chart across a boundary. And the equal arcs are a scheme laid over the sky rather than a description of it: the star the nakshatra is named for sits somewhere inside its arc rather than filling it, and for several nakshatras that identification is itself disputed.
