'DAYA' is the visual outcome inspired by 'Hidden Face of Eve: Women in the Arab World' (1980) written by Nawal El Saadawi.
The daya is a midwife who preforms female circumcision on very young girls and is involved by ‘defloration rituals’ where she puts her long sharp fingernail in the vagina and (supposedly) cuts the hymen. Often and on purpose the nail penetrates the vaginal tissue and the woman bleeds terribly, not to think of the pain and chance of infection.
From chapter 5. The Very Fine Membrane Called ‘Honour’:
“For in many villages this ritual ceremony in honour of virginity is performed by an ugly old crone, the daya who earns her living by amputating the clitoris of children, and tearing open the vagina of young brides. The father of the bride then holds up a white towel stained with blood, and waves it proudly above his head for the relatives assembled at the door to bear witness to the fact that the honour of his daughter and of the family is intact.”
