Nikolai Pokrovskii pioneered in church architecture as a field in archeology. His Master’s on “The Origin of the Ancient Christian Basilica” established the basis for what would become a major archeological question, that is, how did church art and architecutre relate to liturgy. His interest in Orthodoxy meant that he also became a Byzantinist. Moreover, he was a founding member of the monarchist political party “The Russian Assembly” in 1900.
