Gammelion (1968)

Gammelion 1968, filmed at Il Castello Roccasinibalda in Rieti, Italy, is a major work in Markopoulos’s oeuvre, marking the transition into his late period and anticipating his epic final film, Eniaios 1947–91. Shot with only two rolls of film, the work extends seven minutes of footage to almost one hour of viewing time using hundreds of fades in and out. - Tate Modern
