acrylic, canvas, 100 × 99.5 cm
Urbásek’s work during the 1960s still showed the waning influence of informel as well as increasingly reflecting his interest in lettrism and geometric abstraction. In the 1970s his art was characterized by clean, sophisticated geometric compositions, and in the 1980s this clinical geometric precision made way for a different manner of expression, which can also be seen in the canvas entitled O-82-08. The surfaces of Urbásek’s paintings from this period became more prominently sculptured and structured. Geometric shapes were penetrated by diagonal brushstrokes in the form of cross-hatching, and acrylic paints made way for oil pastels. In this late period, Urbásek’s works took on a more spiritual dimension. The aesthetically pleasing geometric interrelations of his preceding creative period evolved into lightly-coloured compositions bordering on the monochromatic. Pure, clean linear shapes were replaced by impasto surface structures and diagonally oriented brushstrokes.
