Which artist, would sometimes go for days, without food or sleep,in an attempt to explore the deep, rooted sources of creativity and truth

Leonardo da Vinci

One artist known for pushing the limits of creativity and truth through extreme dedication is Marina Abramović. She is a performance artist who often goes to extremes in her art. In her most famous work called "The Artist is Present," she sat silently in a gallery for 736 hours over the course of three months, without eating or taking breaks, as a testament to the power of presence and endurance. While Marina Abramović may not have explicitly mentioned going without sleep or food for days in her artistic process, her commitment to exploring profound depths of human experience and pushing physical and mental boundaries resonates with the idea of sacrificing basic needs in pursuit of creativity and truth.
