Remembering Leo Castelli on his birthday, September 4.
A visionary dealer, mentor and longtime friend, Leo Castelli represented Nassos Daphnis for four decades, from 1958 to 1998, presenting his work through numerous exhibitions in New York.
Their relationship was built on loyalty, mutual respect and a shared belief in the importance of Daphnis’s radical abstraction.
