Teatro La Máscara's "Luna menguante" poses a theatrical immersion into women's "intimate and secret" universe. Meshing religious and popular myths, rites, and beliefs, along with music and circus skills, four women of different generations (grandmother, mother, and two daughters) weave a complex fabric of taboos and desires around natural and biological processes --menstruation, deflowering, menopause, senile dementia. Bound by repression and inhibitions, the characters inhabit real and mental spaces in a sordid world dictated by habits and traditions.
