Babara G walker's (FANTASTIC) book ' The Women's Encyclopedia of Myths & Secrets' ( which I totally reccomend - won London Times Educational book of the year 1986)
Says, under 'menstrual cycle':
''two conficting calendars used during mostmof the Christian era in Europe. The church's official solar calendar, and peasants unnofficial, lunar, goddess-given menstrual calendar....
.... Calendar consciousness developed first in women, because of their natural cycle, correlated with observations of the moon's phases. Chinese women established a lunar calendar 3000 years ago...
Gaelic word for 'menstruation' and 'calendar' are the same - 'miosach' and 'miosachan'...
...in generak the symbols of ancient matriarchy came to be known as night, the moon and number 13. While those of patriarchy were day, the sun, and number 12.''
There us so much under the entry it is fascinating, I cant type it all.
I very much reccomend this book. I wonder what an ROGD girl might think to read it.
Maybe we need to start shining some moonlight onto these gender issues.
The very long entry under 'witch hunting' is absolutely mind blowing.
