) use the traditional 12-sign zodiac based on dividing the ecliptic into 12 equal parts rather than the IAU constellation boundaries, and do not regard Ophiuchus as a sign.

There is considerable confusion between the notion of a sign, which is an equal division of the sky into 12 in both the Vedic and the Western systems of astrology, and a constellation, which is a grouping of stars that touches the ecliptic. While Vedic uses a sidereal system based on the stars, that sidereal horoscope is divided evenly into 12 signs which are symbolic of the varying-size constellations they make contact with.

History

Ophiuchus and some of the fixed stars in it were sometimes used by astrologers in antiquity as extra-zodiacal indicators (i.e. astrologically significant celestial phenomena lying outside of the 12-sign zodiac proper). The constellation is described in the astrological poem of Manilius

Manilius may refer to one of the following:*Manius Manilius, consul*Marcus Manilius, Roman poet and astrologer*Gaius Manilius, Roman tribune*Manilius , a Lunar crater, named after Marcus Manilius----...

: the Astronomica, which is dated to around 10 A.D. The poem describes how:
Later in his poem, Manilius describes the astrological influence of Ophiuchus, when the constellation is in its rising phase, as one which offers affinity with snakes and protection from poisons, saying "he renders the forms of snakes innocuous to those born under him. They will receive snakes into the folds of their flowing robes, and will exchange kisses with these poisonous monsters and suffer no harm". A later 4th century astrologer, known as Anonymous of 379, associated "the bright star of Ophiuchus", Ras Alhague

 (α Ophiuchi), with doctors, healers or physicians (ἰατρῶν), which may have been because of the association between poisons and medicines.

Based on the 1930 IAU constellation boundaries, suggestions that "there are really 13 astrological signs" because "the Sun is in the sign of Ophiuchus" between November 29 and December 17 have been published since at least the 1970s.

In 1970, Stephen Schmidt in his Astrology 14 advocated a 14-sign zodiac, introducing Ophiuchus (December 6 to December 31) and Cetus

In January 2011, a statement by Parke Kunkle of the Minnesota Planetarium Society repeating the idea of "the 13th zodiac sign Ophiuchus" made some headlines in the popular press.

Symbol

Schmidt introduced his own symbol for his Ophiuchus sign in 1974. It was a stylized representation of a man carrying a snake.

In 1995 Berg also proposed a symbol for Ophiuchus, and it has come into comparatively widespread use in Japan. In 2009, it was suggested for inclusion in the Unicode
