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 relativistically fixed reference frame of tropical signs used in astrology. All celestial bodies, including stars and constellations, are located within this fixed framework. For example 26 Taurus 07 means 26 degrees 07 minutes of the tropical sign Taurus. See Ecliptic coordinate system for further information.
