An inquisitive artist with a bent for pushing boundaries, Jannis Spyropoulos gave up figurative art in the mid-1950s to explore abstraction. “Dialogue With the Invisible,” on display at the Historical Museum of Crete in Iraklio through January 31, 2018, comprises 13 pieces Spyropoulos painted in the 1960s, when he started gaining a reputation as one of the key proponents of abstract art after being awarded the UNESCO Prize at the 1960 Venice Biennale. Opening hours are Mondays to Saturdays from 9 a.m. to 5 p.m. and admission costs 5 euros.
