History of the star: A star situated in the Cup, Crater, and symbolically called "the Holy Grail". [Fixed Stars and Constellations in Astrology, Vivian E. Robson, 1923].

The astrological influences of the constellation given by Manilius: 

Note: Manilius described Crater as 'gratus Iaccho Crater' (Iaccho is Roman Bacchus who is identified with Greek Dionysus), "so using the mystic, poetical name often applied to Bacchus" (Allen, Star Names)

Good mental abilities. (Fixed Stars and Judicial Astrology, George Noonan, 1990).

"He [those influenced by the Crater in astrology] will join your vines, Bacchus [translator's note; 'grapevines for the production of wine'], in wedlock to your elms; or he will arrange them on props, so that the fronds resemble the figures in a dance or, allowing your vine to rely on its own strength, he will lead it to spread out its branches as arms, and entrusting you to yourself will forever protect you from the bridal bed, seeing how you were cut from your mother (Semele, daughter of Cadmus).

"Whoever derives hence his birth and character [from the constellation Crater] will be attracted by the well-watered meadows of the countryside, the rivers, and the lakes. He will sow corn among the grapes and will adopt any other of the countless forms of cultivation that exist throughout the world as the conditions of the district will require. He will drink without stint the wine he has produced and enjoy in person the well earned fruits of his labors; neat wine will incite him to jollity, when he will drown all seriousness in his cups.
Nor only on the soil will he stake his hopes for paying his yearly vows he will also go in pursuit of the grain tax (become a tax collector), and of those wares (papyrus, for example, or sponges) especially which are nourished by moisture or to which water clings. Such are the men to be fashioned by the Bowl, lover of all that is wet." [Manilius, Astronomica, 1st century AD, book 5, p.318-321].

The general astrological influences of the star: It gives ideality, psychic power, intelligence, honor and riches in disgrace and purifies to salvation. (Robson).
