The exhibition Contra o Muro constitutes the first important group of paintings presented to the Portuguese public by Dumas – and a new step in her oeuvre. A challenging and concerned body of work, Dumas has concentrated for the first time on painting architectural constructions – in this case the 'security wall' between Israel and Palestine, its violence and human tragedy. Paintings, texts and found media emphasise the social reality of segregation, oppression and domination. But these new works also transform into general explorations of death, loss and sacrifice, in a groundbreaking statement for Dumas that is simultaneously political, self-questioning and poetic.
