The political events of the early 1960s, such as the construction of the Berlin Wall and the Cuban missile crisis, which gave new impetus to the cold war between East and West, and the strengthening of civil rights and student movements, especially in the States United (Per Angela Davis, 1972) and West Berlin (Vietnam III with Rudi Dutschke, 1968), found a great deal of resonance in Timner’s work during the decade. From then on, political and social criticism issues have been a focal point in his work.
The Timner series on Chile, painted in 1974, played an important role at this time and was a bitter reaction to the bloody coup in Chile in 1973. This was followed by studies for a series on the civil war in Lebanon (1977). Even the questions of security of peace in Timner’s work constitute a leitmotiv in ever new variants, such as Katharina of Alexandria, 1984, a Christian martyr, a myth based on the historical figure of Hypatia of Alexandria, non-Christian killed by Christians, an indictment against the intolerance of religions.
