In the late 1980s, Sylvestrov became one of the most active members of Lviv’s unofficial art community. In 1990, together with Oleksandr Zamkovskyi, Ihor Shuliev, and Andrii Sahaidakovskyi, he participated in *Defloration*, a landmark exhibition of alternative art curated by Heorhii Kosovan. The project became one of the defining events of the Ukrainian art underground during the Perestroika period.

Sylvestrov was the founder of *Dominism*, an artistic movement in which domino tiles became the primary creative medium. Using ordinary domino pieces, he produced large-scale compositions and objects that reflected on historical memory, political transformation, and personal experience. One of his best-known works is a map of the Soviet Union made entirely of domino tiles, symbolizing both the end of the Soviet era and its critical reappraisal.

From 1994 onward, he lived and worked in Cologne, Germany, while maintaining close ties with the Ukrainian art community. He died in 2018. Platon Sylvestrov’s work occupies an important place in the history of contemporary Ukrainian art as a distinctive example of conceptual artistic practice, combining an austere visual language with a philosophical exploration of history, time, and culture.
