    in western astrology, astrological signs are the twelve 30Âº sectors of the ecliptic, starting at the vernal equinox (one of the intersections of the ecliptic with the celestial equator), also known as the first point of aries. the order of the astrological signs is aries, taurus, gemini, cancer, leo, virgo, libra, scorpio, sagittarius, capricorn, aquarius and pisces. the concept of the zodiac originated in babylonian astrology, and was later influenced by hellenistic culture. according to astrology, celestial phenomena relate to human activity on the principle of "as above, so below", so that the signs are held to represent characteristic modes of expression,mayo (1979), p. 35. or primary energy patterns indicating specific qualities of experience, through which planets manifest their dimension of experience.arroyo (1989), p. 27. the twelve sector division of the ecliptic constitutes astrology's primary frame of reference when considering the positions of celestial bodies, from a geocentric point of view, so that we may find, for instance, the sun in 23Âº aries (23Âº longitude), the moon in 7Âº scorpio (217Âº longitude), or jupiter in 29Âº pisces (359Âº longitude). beyond the celestial bodies, other astrological points that are dependent on geographical location and time (namely, the ascendant, the midheaven, the vertex and the houses' cusps) are also referenced within this ecliptic coordinate system. various approaches to measuring and dividing the sky are currently used by differing systems of astrology, although the tradition of the zodiac's names and symbols remain consistent. western astrology measures from equinox and solstice points (points relating to longest, equal and shortest days of the tropical year), while jyotiá¹£a or vedic astrology measures along the equatorial plane (sidereal year). precession results in western astrology's zodiacal divisions not corresponding in the current era to the constellations that carry similar names,bobrick (2005), p. 10, 23. while jyotiá¹£a measurements still correspond with the background constellations.johnsen (2004). in western and asian astrology, the emphasis is on space, and the movement of the sun, moon and [[planets in astrology|pl
