Tsenov comes out of a detailed source-check, which many of his predecessors have hardly ever seen. It facilitates the reader by printing these source… - Gančo Cěnov

In the time of his reign (Anastasius), the Thracian Vitalian kept under some pretense by using of the exiled bishops, and he took Thrace, Scythia and Moesia, to Varna and Anhialo and led a large number of Huns and Bulgars.

"Tsenov is famous in Italy for his logical Bulgarian erudition, and in Germany, with his previous work, he has revolutionized the origin of the Bulgarians and the other Slavs in the Balkans.... The thesis on the Thracian-Bulgarian origin of the Bulgarians was supported by Tsenov with a great controversial liveliness, which is sometimes quite brave but always rests on arguments that can not be denied without an absolute competence since the author, who has devoted his entire life to this study, does not allow concessions.... He establishes in a complete picture Irvine inhabit life, the language of the Thracians and Illyrians, the ethnic influence that they exercised on the development of the conquering peoples in the Balkans. He concludes in the aboriginal character of the Bulgarians, which is comprehensively addressed and clearly and accurately exposed. All of the work has been examined with a critical chronological and convincing method. He deserves praise. Mr. Tsenov shows that he is a man who has a deep knowledge and a great skill and a man who has put all his love and his whole excitement, who is always inspired by a belief that undoubtedly gives him the right to delight.

If historians who are able to check the facts admit their allegiance, we will have to change some of our beliefs about the origins of Germanism. We have to add that this book is abundant with documents and that some explanations, to say the Christianization of the Goths and the Huns, are very well documented and deserve serious attention.
