The era of Catherine II is revealed through ideas of reason, science, education, and artistic taste. Books, portraits, rare collections, and historical artifacts show how Enlightenment dreams turned into Russian reforms. Catherine's time is read here through objects. The first volume of the "Encyclopedia" by Denis Diderot and Jean le Rond d'Alembert coexists with early editions by Vasily Tatishchev, Mikhail Lomonosov, Nikolai Novikov, and domestic historians of the 18th century. These books remind us that knowledge became not an abstract luxury, but a tool for structuring the state and everyday life. Nearby are silhouette portraits, eglomise, and paintings by Fyodor Rokotov and Dmitry Levitsky. Through them, the era appears not only as theoretical but also visual: with its taste, a fashion for clarity, an interest in human character, and a belief in the power of education. An important line is connected to Catherine II herself. Correspondence with Voltaire and Diderot, support for publishing, journalism, science, architecture, and collecting show a ruler who transformed philosophical ideas into the political and cultural language of the empire. Kolomenskoye adds a personal touch to this conversation. The new palace, garden designs, and the dream of harmony between nature, folk culture, and scientific knowledge bring the grand history of Enlightenment closer: it emerges not only in books and portraits but also in the space where power tried to present its ideal order.
