"Византийская" refers to anything related to the Византийская империя, also known as the Византия, which was the eastern continuation of the Римская империя after its division in the 4th century. This empire lasted for over a thousand years, from 330 AD until 1453 AD, when Константинополь fell to the Османская империя. The term is often used to describe the unique culture, art, and architecture that developed during this period. Византийское искусство is characterized by its religious themes, intricate mosaics, and iconic domed churches, such as the famous Собор Святой Софии.
