not only methods for measuring time; they indicated both the phases of the moon and a woman’s menstrual cycle. Lunar markings found on prehistoric bone fragments show how early women tracked their cycles and planned families in correlation with the phases of the moon. The earliest form of counting "artifacts are menstrual calendar bones, notched with correct lunar cycles, tabulating pregnancy and menstruation." The prehistoric calendar bones include the Ishango bone, the most well known, which was discovered on the shore of a lake in Zaire, Africa, and represented a six-month lunar calendar. The Isturitz Baton represented both a five- and four-month lunar calendar. The Blanchard Bone Plaque represented a two-month lunar calendar. The invention of using beads to family plan is due to the direct correlation of women's menstrual cycles with the lunar cycle. These beads covered in red ochre, which was used in rituals involving nature and perhaps symbolic of menstrual blood, and the animal bones with lunar marking provided the foundations for our elaborate modern mathematic and science systems that took thousands of years for our ancestors to develop. Much of the evidence on lunar calendars are from the Paleolithic period and characterized by the development of venus or feminine figurines. These "exact lunar tallies [that] fall within...a complex storied tradition involving at the center a female creatrix figure and all of her characteristic symbols," according to the anthropologist, Alexander Marshack. Feminine figures, such as Venus of Willendorf and Venus of Laussel, bear traces of having been covered in red ochre. Music Singer and songwriter, Polly Wood, composed an anthem for metaformia called Bledsung. Wood performed Bledsung live at Kuumbwa Jazz Center in Santa Cruz, California for the "Goddesses Sing" show on January 25, 2008. Film 2011 film, Poomarem, which means flowering tree, by Vijay Vipan, illustrates many of the core concepts of metaformic theory. Poomarem focuses on the "menstrual origins of sciences and arts, such as geometry, time, painting, and cooking; and also the violence, and the isolation that inevitably accompany the loss of women's rituals within a society." Vipan states that this film is "A new relational origin story that women's menstrual rituals are the roots of human culture and that in human evolution women and men have markedly different relationships to blood." This film was shown at the 2011 Rotterdam International Film Festival held in Rotterdam, the Netherlands. See also Female cosmetic coalitions The
