Behenian fixed star

The Behenian fixed stars are a selection of fifteen stars considered especially useful for magical applications in the medieval astrology of Europe and the Arab world. Their name derives from Arabic bahman, "root," as each was considered a source of astrological power for one or more planets. Each is also connected with a gemstone and plant that would be used in rituals meant to draw the star's influence (e.g., into a talisman). When a planet was within six degrees of an associated star, this influence was thought to be particularly strong.

Heinrich Cornelius Agrippa discussed them in his Three Books of Occult Philosophy (Book II, chapters 47 & 52) as the Behenii (singular Behenius), describing their magical workings and kabbalistic symbols. He attributed these to Hermes Trismegistus, as was common with occult traditions in the Middle Ages. Their true origin remains unknown, though Sir Wallis Budge suspects a possible Sumerian source.

The following table uses symbols from a 1531 quarto edition of Agrippa, but other forms exist. Where the name used in old texts differs from the one in use today, the modern form is given first.

1 These locations are given in celestial longitude, the relatively fixed reference frame of tropical signs used in astrology and are derived from the measurements listed at Constellations of Words. Due to Precession of the Equinoxes the Fixed Stars appear to drift or move through space at the rate of 1 degree of Arc per 72 years. In order to fix the measurement to a specific date and degree of arc the values published through that scholarly work are utilized for the year 2000. All celestial bodies, including stars and constellations, are measured according to various fixed frameworks, in this instance a geocentric tropical zodiac. Cf. Heliocentric model as a fixed framework and sidereal and tropical astrology to identify the measuring system used here. For example, 26 Taurus 10 means 26 degrees 10 minutes of the tropical sign Taurus. See Ecliptic coordinate system for further information.

2 For the purposes of Behenian Fixed Stars the Star known as Alpha Leo or Cor Leonis, also known as Regulus, should be considered under the auspices of the differences noted in zodiacs as listed above, sidereal versus tropical. In November 2011, through the process of precession, Regulus or the "Heart of the Lion" found itself aligned with 0 Degrees Virgo according to the Tropical Zodiac, which uses the Vernal Equinox as a fiduciary point of reference. In the Sidereal System Regulus is still considered very much within the Sign and the Constellation Leo, but in the Tropical System, relatively recently, the Star is no longer in the Sign of Leo but instead is measured as being in the Sign of Virgo.
