Because of theological themes in his work, Knap became a victims of the political persecution of Catholic intellectuals by the Communist government in the 1950s.
In 1952, he was condemned without any evidence to eleven years in prison, but was released early in 1955 (he was pardoned in 1967 during a brief period of political freedom).
Based on his work in this area, he published Umělcové na pouti (Czech Traveling artists) in 1961.
His inspiration came from northern European authors and some Czech writers, above all Antal Stašek, Karel Václav Rais and the impressionist Fráňa Šrámek.
