History of the star: A star in the Sea Goat's tail, Capricornus. Symbolically called the "Judicial Point of the Goat". Deneb Algedi is the transcription by Ulug Beg's translator of Al Dhanab al Jady (1), the "Tail of the goat"; changed to Scheddi in some lists, — a name also found for gamma (Nashira). Ideler said that these stars (Deneb Algedi and Nashira) were Al Muhibbain, "the Two Friends", an Arabic allegorical title for any two closely associated objects; but Beigel differed with him as to this, and wrote it Al Muhanaim, "the Two Bending Stars", in the flexure of the tail [and adding "for moral beings are foreign to the nomad sky", which could refer to the lusty goat embodied in the god Pan who preyed sexually on nymphs and boys indifferently. Pan was god of All Things, indicative of the procreative charging all things - PDS p.734. The "higher" attributes of Capricorn are personified in Vesta, to whom the sacred Vestal Virgins are consecrated].

With gamma (Nashira) it was Al Sa'd al Nashirah, the "Fortunate One", or the "Bringer of Good Tidings".

It marked the 28th ecliptic constellation of Babylonia, Arkat sha hi-na Shahu, the "Eastern One in the Tail" of the Goat. 

[Star Names, Their Lore and Meaning, Richard Hinchley Allen, 1889].

The astrological influences of the constellation: The Goat is associated with the Hebrew letter Yod and the 10th Tarot Trump, The Wheel of Fortune". (Robson*).

The astrological influences of the constellation given by Manilius:

In her shrine Vesta tends your fires, Capricorn : and from her you derive your skills and callings. For whatever needs fire to function and demands a renewal of flame for its work must be counted as of your domain. To pry for hidden metals, to smelt out riches deposited in the veins of the earth, to fold sure-handed the malleable mass—these skills will come from you, as will aught which is fashioned of silver or gold. That hot furnaces melt iron and bronze, and ovens give to the wheat its final form, will come as gifts from you. You also give a fondness for clothes and wares which dispel the cold, since your lot falls for all 241 time in winter's season, wherein you shorten the nights you have brought to their greatest length and give birth to a new year by enlarging the daylight hours. Hence comes a restless quality in their lives and a mind which is often changed and floats this way and that; the first half of the sign is the slave of Venus, and that with guilt involved, but a more virtuous old age is promised by the conjoined fish below. [Astronomica, Manilius, 1st century AD, book 4, p.241.]
