The icon collection of Pavel Tretyakov reveals the founder of the gallery as a careful researcher of ancient Russian painting. Rare artifacts and archival materials show how the personal interest of the collector became part of the history of the national museum. Icons held a special place in Pavel Tretyakov's collection: they were not just acquired as antiquities, but studied, compared, and introduced into the museum context. Thus, the private collection transformed into a testament to a great artistic tradition. The exhibition features over 60 works from the 15th to the 19th centuries. Among them are the Novgorod "The Queen Appearing", "The Mother of God of Tenderness (Igorevskaya)", and works by royal and Stroganov masters. Many items remained known only to specialists for a long time, so encountering them helps to see the early history of the gallery in a different light. A separate narrative is connected to the 1890s, when the collection was formed with the participation of antiquarians and connoisseurs of antiquity. An important part of the story leads into the 20th century. An international exhibition from 1929 to 1932 made the Russian icon noticeable to the international public, and photographs and documents return the scale of this event. Entertainment in Moscow is collected on KUDAGO.
