Lips of Thomas by Marina Abramovic (1975) Stark naked, she ate a kilo of honey, drank a litre of red wine, carved a pentagram onto her stomach using razor blade, whipped herself, and lay down on a cross made of ice for half an hour, bleeding copiously.
Marina Abramovićand Ulay Breathing In / Breathing Out, 1977
This performance consisted of the two artists seated in front of each other, connected at the mouth. They took in each other’s breaths until all of their available oxygen had been used up. The performance lasted only 17 minutes, resulting in both artists collapsing unconscious to the floor, having filled their lungs with carbon dioxide. This personal piece explored the idea of an individual’s ability to absorb the life of another person, exchanging and destroying it. (Wikipedia)
