Piscis Austrinus Astrology

Manilius

Then rises the Southern Fish in the quarter of the wind after which it is named.

When the Southern Fish rises into the heavens, leaving its native waters for a foreign element, whoever at this hour takes hold of life will spend his years about sea-shore and river-bank he will capture fish as they swim poised in the hidden depths; he will cast his greedy eyes into the midst of the waters, craving to gather pellucid stones and, immersed himself, will bring them forth together with the homes of protective shell wherein they lurk. No peril is left for man to brave, profit is sought by means of shipwreck, and the diver who has plunged into the depths becomes, like the booty, the object of recovery. And not always small is the gain to be derived from this dangerous labor  pearls are worth fortunes, and because of these splendid stones there is scarcely a rich man left. Dwellers on land are burdened with the treasures of the sea. A man born to such a lot plies his skill along the shore; or he purchases at a fixed wage another’s labor and sells for a profit what it has brought him, a pedlar in the many different forms of sea products. ^[1]

Legend. This constellation is said to commemorate the transformation of Venus into the shape of a fish on one occasion when bathing.

Influence. Ptolemy gives no separate influence and describes Fomalhaut, but according to Bayer the constellation is of the nature of Saturn. It is said to have an influence similar to Pisces, but in addition to augment the fortunes. ^[2]

Piscis Australis, the Southern Fish… lies immediately south of Capricorn and Aquarius, in that part of the sky early known as the Water… it is very unnaturally drinking the whole outflow from the Urn. This idea of the Fish drinking the Stream is an ancient one, and may have given rise to the title Piscis aquosus, found with Ovid and in the 4th Georgic.

In early legend our australis was the parent of the zodiacal two, and has always been known under this specific title, varied by the other adjectives of equivalent signification, austrinus, meridionalis, and notius.

When the Arabians adopted the Greek constellations and names this became Al Ḥūt al Janūbiyy, the Large Southern Fish, distorted in late mediaeval days into Haut elgenubi, and given by Chilmead as Ahaut Algenubi; but their figure was extended further to the south than ours, and so included stars of the modern Grus.

Bayer said that it partook of the astrological character of the planet Saturn.

Gould assigns to it 75 naked-eye components. ^[3]

Bullinger

This first constellation is one of high antiquity, and its brilliant star of the first magnitude was a subject of great study by the Egyptians and Ethiopians. It is named in Arabic Fom al Haut, the mouth of the fish There are 22 other stars. The constellation is inseparable from AQUARIUS. In the Denderah Zodiac it is called Aar, a stream. ^[4]
