The autobiographical novel “Portrait of the Invisible,” which is also a lament for a deceased friend, depicts the life of European bohemia in the last quarter of the 20th century - a life imbued with the spirit of beauty and the ability to enjoy the moment. In his comprehensive panorama of the cultural avant-garde from the 1970s to the 1990s, the author includes witty sketches of all the famous contemporaries he encountered—an incomparable treat for those familiar with the milieu he describes. The reader is presented with a unique portrait of an era that cultivated the ability to transform life into a continuous celebration, but at the same time, it was distinguished by a tragic foreboding of the decline of European culture.
