Anoster
Anoster: According to the Testament of Solomon, Anoster is one of thirty-six demons tied to the decans of the zodiac. Specifically, he is number twenty-nine. All of the zodiac demons named in the Testament of Solomon are depicted as disease-bearing spirits that torment humanity with specific ailments. In Anoster's case, he has the power to afflict his victims with infections of the uterine and urinary tracts. He is also attributed with the ability to cause something called “uterine mania” in the text- which seems to suggest that he is, in fact, the demon behind PMS. As great as the suffering Anoster brings may be, he can be driven away from his victims through the use of the name Marmarao.
