Tetrabiblos and Centiloquy

They imitate the powers [of the planets]. In the alathaoriginal: "alatha"; likely a corruption of the Arabic term for the "shoulder" or "wing" of a constellation where it is located, which bears a resemblance to the clouds and follows it, they do not depart from the powers of Mars and the Moon. ¶ Likewise, the stars in Sagittarius: those which indicate the tip of the arrow equal the powers of Mars and the Moon. Of those which express the form of the bow itself, and those which figure in the place where the hand touches it, they work as Jupiter and Mars. Those, however, which are in the alatha of its face, agree with the works of the Sun and Mars. Of those which are in the place of the arrow, their contracted powers equal the powers of Jupiter, and although moderately, they agree with the works of Mercury. In its legs, however, those situated there do not set aside the powers of Jupiter and Saturn. The four, however, which are in its tail, are likened to the powers of Venus and Saturn. ¶ Also the stars of Capricorn which cling to its horns do not depart from a Venerian of Venus complexion, and they follow the Martial of Mars although but little. Their works, however, which are seen in its mouth, equal Saturnine works and moderately also those of Venus and Mars; and those formed in its tail do not differ from the powers of Jupiter and Saturn. ¶ Likewise in Aquarius: the stars which are in its water-pot original: "hauritorio" along with those figured in the left hand, work just as Saturn and Mercury. But the powers of those in the hips, which are many, do not dissent from Mercurial works; a very few of them are likened to Saturnine powers. In the downward flow of the water, those placed there imitate Saturn in their works and receive a little from the complexion of Jupiter. ¶ Of the stars arranged in Pisces: those which occupy the top of the southern fish do not discord from the powers of Mercury, and although moderately, they follow the powers of Saturn. In its mouth, those seen do not cease to work according to the likeness of Jupiter and Mercury; those situated upon its tail and upon the southern thread the cord connecting the two fish do not differ from the complexions of Saturn, and although a little, they are likened to the powers of Mercury. Likewise the works of those in the body of the northern fish itself—namely, in its spine—do not reject the works of Jupiter and somewhat imitate Venus. In the northern thread, those fixed work like Saturn and Jupiter.

The bright star situated above its knot the point where the two cords of Pisces meet bears the likeness of Mars and a little of Mercury.
¶ Likewise, let us speak of the stars which are in the northern figures outside the circle of the signs the Zodiac.
Stars indeed bright, formed in Ursa Minor the Little Bear, do not depart from the powers of Saturn, and they embrace Venerian qualities, although but little. In Ursa Major the Great Bear, those located there agree with the complexions of Mars. ¶ The stars likened to the smaller alatha, shaped under its tail, do not dissent from the complexions of Venus and the Moon. ¶ The bright stars which signify the place of Draco the Dragon equal the powers of Saturn and Mars. ¶ The qualities of those in Cepheus do not discord from the qualities of Jupiter and Saturn. Placed in the michalikely "mica" or "massa," referring to a specific part of the back or shoulder of its back, they do not set aside the powers of Mercury and Saturn; indeed, they even sometimes follow the powers of Jupiter and Mars. ¶ The bright star possessing a red color, which is called Azimech ArtamecArcturus, carries the likeness of Jupiter and Mars. ¶ But those in AlfeltaCorona Borealis exist as similar to Venus and Mercury. ¶ Those which are situated in the Man Sitting on His Knees Hercules do not turn their face away from Mercurial complexions. ¶ Certain of those also in AlflageLyra, which is called the Falling Vulture, do not cast away the powers of Venus and Mercury. ¶ Those which express the form of the Hen Cygnus, the Swan are likened to these aforementioned. ¶ But that figure which occupies the place where the Seat Cassiopeia is, equals Saturn and Venus. ¶ The stars which are said to be of that which is carried—the Head of the Chained Woman Andromeda—do not reject the works of Saturn and Venus; and those which hold the likeness of the alatha which is contained in the handle of the knife m. r. likely a marginal reference or correction mark imitate Martial and Mercurial complexions. The bright stars of that figure in which the borders are formed do not depart from the powers of Mars and Mercury. ¶ Likewise the works of the stars which represent the image of the Man Holding the Serpent Ophiuchus are likened to Saturnine works and a little of Venus; those fixed in the body of the serpent itself [work] from Saturn and Mars in their works.
