"Tsenov comes out of a detailed source-check, which many of his predecessors have hardly ever seen. It facilitates the reader by printing these sources in the original.... From the same sources, it can be seen that the Bulgarians were south of the Danube for 350 years and so they did not come until 679 from the Volga before the Slavs and also before the Huns in Illyria and Thrace. The Bulgarians lived in 350 AD. along the lower Danube in the Byzantine Empire south of the lower Danube. They were a mighty people, not only in Moesia but also in Thrace and Illyria.""
