The legend of adoption of Christianity in Russia as stated in the Chronicle of Years and Times has it that the unprecedented beauty of divine service was the main reason for choosing the Byzantine model of Christian faith. Church singing heard by Prince Vladimir’s ambassadors in Constantinople amazed them with its delightful beauty. The Byzantine aesthetics inheriting the Platonic doctrine of identity of beauty, truth, and deity proved to be very close to the heart of ancient Slavs, and had a tremendous impact on generation of a new professional singing culture in Russia.
