Mysteries of Isis

Mysteries of Isis.
The mysteries of Isis were religious initiation rites performed in the cult of the goddess Isis in the Greco-Roman world. Alluding to the worship of Isis from ancient Egyptian religion, they were modeled on other mystery rites, particularly the Eleusinian mysteries, which honored the Greek goddess Demeter. By undergoing the mystery rites, initiates signaled their dedication to Isis. Many texts from the Roman Empire refer to the Isis mysteries, but the only source to describe them is a work of fiction, the novel The Golden Ass, written in the second century by Apuleius. In it, the initiate undergoes ritual purification before descending into the innermost part of Isis's temple, where he experiences a symbolic death and rebirth and has an intense religious experience. Some aspects of the mysteries of Isis and of other mystery cults resemble elements of Christianity, but the evidence for their influence on Christianity is unclear.

Menstrual cycle

Menstrual cycle.
The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries of the female reproductive system that make pregnancy possible. Naturally occurring hormones drive two concurrent and coordinated cycles that last about 28 days. The ovarian cycle controls the production and release of eggs and the release of the hormones estrogen and progesterone. The uterine cycle governs the preparation and maintenance of the lining of the uterus (endometrium) to receive a fertilized egg. Menstruation, a "period" in common parlance, begins on day one of the cycle, and lasts for about five days. Around day fourteen, an egg is usually released from the ovary. Estrogen stimulates the uterus lining to thicken to accommodate an embryo should fertilization occur. If implantation does not occur, the lining is released during menstruation. Menarche (the first period) usually occurs around age twelve, and menstrual cycles usually continue for 30–45 years until menopause.

Yazid I

Yazid I.
Yazid I (c. 646 – 683) was the second caliph of the Umayyad Caliphate, ruling from April 680 until his death. His appointment, the first hereditary succession to the caliphate in Islamic history, was opposed by several Muslim grandees from Medina, including Muhammad's grandson Husayn ibn Ali. Husayn refused to recognize Yazid following his accession and left for Kufa in Iraq to lead a revolt, but was killed in the Battle of Karbala. To suppress the subsequent rebellion in Arabia, Yazid sent an army that captured and sacked Medina. Next, Mecca was besieged for several weeks until the army withdrew as a result of Yazid's death. The caliphate fell into a decade-long civil war known as the Second Fitna, ending with the establishment of the Marwanid dynasty. Yazid is considered an illegitimate ruler and a tyrant by many Muslims. Modern historians consider him a capable ruler, albeit less successful than his father Mu'awiya I, whose style of governance he continued.
