Agrippa's Three Books of Occult Phillosopy 09
The ennead–9–was the first square of an odd number (3x3). It was associated with failure and shortcoming because it fell short of the perfect number 10 by one. It was called the called the number of man, because of the nine months of his embryonic life. Among its keywords are ocean and horizon, because to the ancients these were boundless. The ennead is the limitless number because there is nothing beyond it but the infinite 10. It was called boundary and limitation, because it gathered all numbers within itself. It was called the sphere of the air, because it surrounded the numbers as air surrounds the earth, Among the gods and goddesses who partook in greater or less degree of its nature were Prometheus, Vulcan, Juno, the sister and wife of Jupiter, Paean, and Aglaia, Tritogenia, Curetes, Proserpine, Hyperion, and Terpsichore (a Muse).
The 9 was looked upon as evil, because it was an inverted 6. According to the Eleusinian Mysteries, it was the number of the spheres through which the consciousness passed on its way to birth. Because of its close resemblance to the spermatozoon, the 9 has been associated with germinal life.
Of the Number Nine, and the Scale thereof
The number nine is dedicated to the Muses, by the help of the order of the Celestial Spheres, and divine spirits Hence there are nine movable Spheres, and according to those there are nine Muses, viz. Calliope, Urania, Polyhymnia, Terpsichore, Clio, Melpomene, Erato, Euterpe, Thalia, which nine Muses indeed are appropriated to the nine Spheres, so that the first resembles the supreme Sphere, which they call Primum mobile, and so descending by degrees, according to the written order, unto the last, which resembles the Sphere of the Moon, so, viz. Calliope is appropriated to the Primum mobile; Urania to the Starry Heaven, Polyhymnia to Saturn, Terpsichore to Jupiter, Clio to Mars, Melpomene to the Sun, Erato to Venus, Euterpe to Mercury, Thalia to the Moon.
There are also nine orders of blessed Angels, viz. Seraphim, Cherubim, Thrones, Domination, Powers, Virtues Principalities, Archangels, Angels, which Ezekiel figures out by nine Stones, which are the Sapphire, Emerald, Carbuncle Beryl, Onyx, Chrysolite, Jasper, Topaz, Sardis: The number hath also a great, and Occult mystery of the Cross: For the ninth hour our Lord Jesus Christ breathed out his Spirit.
And in nine days the Ancients buried their dead, and in so many years they say Minea received Laws from Jupiter in a Cave; whence this number was most especially taken notice of by Homer, when Laws were to be given, or answers were to be given, or the sword was like to rage.
The Astrologers also take notice of the number nine in to Ages of men, no otherwise then they do of seven, which they call Climactericall years, which are eminent for some remarkable change. Yet sometimes it signifies imperfectness and incompleteness, because it doth not attain to the perfect on of the number ten, but is less by one, without which it deficient, as Austin interprets it of the ten Lepers: Neither the longitude of nine Cubits of Og King of Basan, who is a type of the devil, without a mystery.
