moon The moon is the most ‘human’ of the heavenly bodies, since its phases and the shadows on its surface give it a face, encouraging the popular lore about the ‘Man in the Moon’. Belief that the moon has a special influence on human affairs has been universal. Because of its phases, it has been linked to the rhythms of life and to nature's cycles: water, rain, and
fertility. ‘The moon has great influence in vulgar philosophy’, observed Samuel Johnson, touring the Scottish Highlands, ‘In my memory it was a precept annually given in one of the
English Almanacks,
to kill hogs when the moon was increasing, and the bacon would prove the better in boiling.’
Many religious beliefs have been woven around the moon, which has commonly been personified as a goddess. She is
Ishtar to the Babylonians,
Asthoreth to the Phoenicians, and, to the Greeks,
Artemis (Roman
Diana), the chaste huntress who cruelly punished those who failed to worship her.
Three main connotations have been ascribed to the moon. It has stood for the feminine principle. Being smaller than the sun and reflecting its light, the moon has been taken to represent female dependence and passivity. In Taoist terms, the moon is thus
yin, being receptive, relative to the sun's
yang. Amongst the Inca, the moon was the sun's wife, and hence the goddess of women. Its waxing and waning has also served as an analogue for supposed female fickleness.
The moon has also been regarded as controlling
menstruation. According to the eighteenth-century physician, Richard Mead, ‘everyone knows how great a share the Moon has in forwarding those evacuations of the weaker sex.’ The very word menstruation means ‘moon change’, while in France it is called ‘le moment de la lune’. In Saibai and Yam, two islands off Australia, it was believed that menstruation was caused by the moon, who came as a man to seduce the pubescent girl.
Menstrual seclusion rituals are thus commonly governed by the lunar phases. The Juluo of East Africa believe that menstruation comes with the new moon and that only then can women become pregnant. There have been evolutionary speculations that since the lunar and the menstrual cycles each are of approximately 28 days' duration, menstruation is causally related to the action of the moon on the tides, somehow dating back to the time when we were all sea creatures.
Finally, the moon has been judged to be the cause of madness, the term ‘lunacy’ deriving from the Latin
luna, meaning moon. Hippocrates, Pliny the Elder, Plutarch, and the Bible all affirmed its harmful influence. Aretaeus of Cappadocia and Rhazes held that epileptic seizures were governed by the moon, while Hildegard of Bingen deemed that ‘a male born on the seventeenth day of the Moon will be an idiot.’ Shakespeare affords many references to the Moon as the ‘sovereign mistress of true melancholy’:It is the very error of the moon,
She comes more near the earth than she was wont
And makes men mad. (
Othello)
As late as 1791, the French psychiatrist Joseph Daquin wrote in his
Philosophie de la Folie that ‘it is a well established fact that insanity is a disease of the mind upon which the moon exercises an unquestionable influence.’ His younger contemporary, Jean Esquirol, concluded that the moon affected the insane through its light, which excited some and terrified others. Although such beliefs have waned, many modern studies have investigated the significance of the phases of the moon in relation to
suicide,
murder, mental hospital admissions,
violence,
migraine,
anxiety, childbirth, and marital breakdown.
