History of the star: A star in the right eye of the Goat Capricornus. Oculus is Latin for "eye".

The astrological influences of the constellation: The Goat is associated with the Hebrew letter Yod and the 10th Tarot Trump, The Wheel of Fortune". (Fixed Stars and Constellations in Astrology , Vivian E. Robson, 1923)

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.]

With Mercury: Clever and piercing intellect. (Robson).
