 Two pilgrimages and two works by Dmitri Rostovsky, an archbishop who influenced Ukrainian and Russian literature by composing groundbreaking religious plays, strengthened his beliefs.Through his visits to western Europe and discussions with Herzen, Grigoriev, and Strakhov, Dostoevsky discovered the "Pochvennichestvo" movement and the theory that the Catholic Church had adopted the principles of rationalism, legalism, materialism, and individualism from ancient Rome and had passed on its philosophy to Protestantism and consequently to atheistic socialism.Dostoevsky's canon includes novels, novellas, novelettes, short stories, essays, pamphlets, limericks, epigrams and poems.
