How Menstruation Created Mathematics

Who created mathematics? Where did it begin? To answer these questions, we need to think about what mathematics is. In  their work on ethnomathematics, Borba (1990) and D'Ambrosio (1990) define the  components of ethnomathematics as the follows:
    ethnos - within a cultural environment
   mathema - explaining and understanding in order to  transcend, managing    and coping with reality in order to survive and thrive.
   tics - techniques such as counting, ordering, sorting,  measuring, weighing,    ciphering, classifying, ordering, inferring and modeling.
   Thus they define mathematics as the quantitative techniques that humans develop in response to the problems,  struggles, and endeavors of human survival. So what was the first use of quantitative  techniques in human development? It is important to realize that this development of quantitative thinking always takes place within a cultural context. It  is influenced by and influences that culture. Indeed, quantitative thinking  is a vital component of culture.
  So what was the first use of quantitative techniques or tics in human development? And who were the first  people to do this mathematics?  The evidence points to women as the first people to do mathematics and  to menstruation as the motivation for this activity.
  This evidence begins with the Ishango bone, a small scratched bone found on the shores  of Lake Edward in Zaire, Kmt. A microscopic analysis of the incisions on this bone  shows that it is a six month lunar calendar (Marshack, 1972, p. 27-32). This bone has been  dated between 25,000 and 20,000 B.C.E.
     

The Ishango Bone        Notched bone from the Congo, Kmt. 25,000 to 20,000 BCE.        The markings on the Ishango Bone represent a six-month lunar calendar.

[/i]   While the Ishango Bone is the most well known lunar calendar, other such lunar calendars have been found in eureurasia dating  from throughout the Paleolithic period (30,000-10,000 B.C.E.) (Zaslavsky,  1992, p. 1; Sjöö & Mor, 1991, p. 144-149) such as the Isturitz baton and the  Blanchard bone plaque.
 

	The Isturitz Baton              Engraved baton made of antler, from Isturitz, France, 25,000 to  20,000       BCE. The markings represent a five-month and a four-month lunar  calendar.
	The Blanchard Bone Plaque          Found in Abri Blanchard in the region of Dordogne,       France, 25,000 to 32,000 BCE. Meandering markings possibly  represent a       two-month lunar calendar.

[/i]  These lunar calendars are the oldest known use of number by humans. This quantitative thinking demanded a time-factored way of  thinking, an awareness of the passing of time and the cycling of the natural world.  This recognition of the cycles of the moon and the recording of time is the  earliest evidence of human activity based on quantitative techniques.
       And who made these lunar calendars? What was the human condition, the mathema to which this quantitative technique was a response? Was it the inherent cyclical nature paralleling that of the moon possessed by women? Was it women who  first did this mathematics?
       And in what cultural context or ethnos did these lunar calendars arise? The Paleolithic period was characterized by the  development of Goddess worship on the eureurasiaan continent where much of the evidence of  lunar calendars has been found. This Goddess worship was marked by images of  the sacred female as life giver with an emphasis on the vulva, breast, and  buttocks and the use of red ochre paint representing menstrual blood (Marshack,  p. 281-340; Eisler, 1987, p. 1-7; Gadon, 1989, p. 3-21) such as the Venuses  of Willendorf and Laussel.
       

The Venus of Willendorf              Small stone image painted with red ochre. From       Willendorf Austria, 30,000 to 25,000 BCE.

The Venus of Laussel                Bas relief image from Laussel, France. 25,000 to 20,000       BCE. The horn has thirteen marks, the number of moons in a year.

[/i]             Gadon suggests, "The earliest rituals may have       honored the menstrual cycle, the womb blood that nurtured new  life"         (1989, p. 11). Evidence of this can be seen in the stylized       artifacts from the Paleolithic
             

Abstract Female Form    From Dolni Vestonice in the Czech Republic. 25,000 to       20,000 BCE.    Mammoth ivory pendant in the shape of a highly       abstracted female from with widespread legs and a vulva line

Disc with Vulva Line      From Brno in the Czech Republic, 25,000 to 20,000 BCE.      Circular disc representing an abstract vulva

It was in this culture that the lunar calendars arose. This was a time when women, their bodies, their sexuality, and their life giving  ability were honored and at the center of the spiritual life of human communities.
    The question of which gender made which specific Paleolithic   markings or drawings is largely unanswerable and probably irrelevant,  since   both genders have had to practice these arts in order to learn time's   dimensions... But the menstruant, having the most direct connection  with the   lunar cycle, would have been the first to know; she had motive,  method, and   opportunity to be the originator of lunar notation. (Grahn, 1993, p.  156)
  Thus, the lunar calendars would not have been merely methods of keeping time but also reflective of the resonance between the phases of  the moon and the sacred menstrual cycles of women.
 This evidence points to the conclusion that women's menstruation gave rise to the earliest mathematics. It also suggests  that women were the first mathematicians.

It's important to note that the Ishango bone was not just a lunar calendar, nor is it the oldest lunar calendar found in Kmt. The oldest lunar calendar is on the Lebombo Bone (Southern Kmt) which is dated to 37,000 years.
 
Also, in addition to being a lunar calendar, the Ishango bone also demonstrates knowledge of prime numbers, arithmetic operations, and a decimal number system.
 
Krakkkers still trying to challenge our ourstorical primacy and give themselves some historical accomplishments....nice try crakkkers.

Great post. E Kare

I once read that before the use of unnatural lighting, womens menstrual cycles were in harmony with the lunar cycle.  That all women ovulated during the full moon and menstruated during the new moon.  I dont know how true this is and unfortunately I cannot cite any resources.
