Maria-Conception-Action: Hermann Nitsch  

"In the "Maria-Conception-Action", the eroticisation and desublimation of the idea of redemption is intensified into pornography ... it complements the flesh of the lamb carcass with that of the female nude and is crucified allegorically like the lamb and together with it. The slitting open and evisceration of the lamb carcass corresponds visually to the opening and pushing apart of the vagina; the defilement and dismemberment of the lamb corresponds to the pouring over or covering of the nude female body with blood and entrails, and finally, to the sex act itself, which Nitsch -- again in an allegorically obscene substitute act -- completes with a godemiche." --Sexualästhetik (1972) by Peter Gorsen
