The work "kairos" is a gouache-painting on the walls of the Museum in Viersen, Germany, for the Group-Exhibition „schwarz/weiß“ (‚black/white‘). It takes place in the beginning of the lockdown for corona in march 2020. I was lucky to work at an „abandoned“ Museum: no visitors, all alone with the work of Rembrandt and others, quietly working. I used my scetches of the cycle „Niemehr schlafen“ (‚nevermore sleeping‘). But the title of this particular work was ‚kairos‘ - because of the special moment of working. The ancient Greeks had two words for time: chronos and kairos. The chronological or sequential time, and a proper or opportune time for action. While chronos is quantitative, kairos has a qualitative nature.
