Sophie Dupont’s Performance ‘Marking Breath’ explores the ritual repetition of the most important and simple action in life: breathing.The perfor- mance contains no plot, no story, no narrative progression – only body, breath, marks and time. The work is meditative and reductive in form and content exploring the discrete/invisible sign of presence and existence, breath, and transforming it into physical/visible marks.The duration of the performance is usually from sunrise to sunset.
