History of the star: A star in the flank of Aries, the Ram. Botein is from Al Butain (1), "The little belly", the dual of Al Batn, the Belly, probably from some early Arabic figuring, for in modern maps the star lies on the tail. This star delta, with epsilon and rho³, generally were considered the 28th Arabic manzil, Al Butain 

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

Influences of the 28th Arabic manzil, Al Butain: Helps the finding of treasures and retaining of captives. With Moon transiting here; buy and sell but avoid the sea.

The astrological influences of the constellation: The Ram is associated with the Hebrew letter He and the 5th Tarot Trump "The Pope". (Fixed Stars and Constellations in Astrology, Vivian E. Robson, 1923)

"All the Aries stars have been in the sign Taurus for 200-300 years now. Hamal just over 600, (Botein year 505AD)  and in this same period we have seen large-scale aggression change its nature from barbaric raiding and migration of earlier centuries to the building of large empires which had to be administered and kept in peace and good order, as well as exploited by their conquerors. This is typical both of the sign Taurus and of the planet Saturn". (The Living Stars, Dr. Eric Morse).

The astrological influences of the constellation given by Manilius:

"The Ram, who is rich with an abundance of fleecy wool and, when shorn of this, with a fresh supply, will ever cherish hopes; he will rise from the sudden shipwreck of his affairs to abundant wealth only to meet with a fall, and his desires will lead him to disaster; he will yield his produce for the common benefit, the fleece which by a thousand crafts gives birth to different forms of gain, now workers pile into heaps the undressed wool, now card it, now draw it into a tenuous thread, now weave the threads to form webs, and now they buy and sell for gain garments of every kind; no nation could dispense with these, even without indulgence in luxury. So important is this work that Pallas herself has claimed it for her own hands, of which she has judged it worthy, and deems her victory over Arachne a token of her greatness. These are the callings and allied crafts that the Ram will decree for those born under his sign: in an anxious breast he will fashion a diffident heart that ever yearns to commend itself by its own praise. When the Ram emerges above the surface of the waves (rising) and the curve of his neck appears before his horns, he will give birth to hearts that are never content with what is theirs; he will engender minds bent on plunder and will banish all sense of shame: such is their desire for venture. Even thus does the ram himself rush forth with lowered horns, resolved to win or die. Not for them the gentle ease of a fixed abode with none but peaceful cares; it is ever their delight to travel through unknown cities, to explore uncharted seas, and enjoy the whole world's hospitality. The Ram himself gives you evidence of this: once furrowing a trail through the glassy sea, he tinged it with the gold of his fleece, when on his back he carried Phrixus, bereft of his sister (Helle) by fate's decree, and brought him to the banks of the Phasis and to Colchis". [Astronomica, Manilius, 1st century AD, book 4, p.233].
