We have seen how in 1333-1334 Stagno and the peninsula of Sabbioncello and the coast as far as the Narenta’s mouth were acquired. In 1357 small additions were made about Breno and Gionchetto between the Ljuta stream and the village of Kurilo[187] (north of the Ombla). The districts of Carina and Drieno, although on the Ragusan side of the mountain above Breno, remained beyond the frontier: eventually they became Turkish territory, and such they remained until 1878.[188] [Illustration: CLOISTER OF THE FRANCISCAN MONASTERY] The Ragusan Church had also been increasing in wealth and dignity with the growth of the Republic, and a number of handsome ecclesiastical buildings were begun during the fourteenth century. In the eleventh, twelfth, and thirteenth centuries the Slavonic princes gave the churches many valuable gifts of land, gold and silver ornaments, and relics. But in the thirteenth and fourteenth centuries Bosnia, Hlum, and Servia were torn by religious wars owing to the spread of that strange and little known heresy called Bogomilism, on which it will be useful to say a few words. Of the origin of this heresy as of its tenets there is very little reliable evidence. In all probability it was an offshoot of Armenian Paulicianism, itself derived from the earlier Adoptionist creed.[189] Paulician colonies have been settled in Europe as early as the ninth century by the Emperor Constantine Copronymus, and the heresy spread to Bulgaria, Servia, Bosnia, and Macedonia. In his History of the Bulgarians, Prof. C. J. Jireček gives an account of the beliefs of the Bogomils according to the researches of various Slavonic scholars. They believed in the existence of two principles, equal in age and power, one good personified in God, and one evil personified in Satan. They recognised the New Testament, but not the Old. All matter and all the visible world were essentially evil; the body of Christ was only an apparent, not a real, body. The sacraments were corporeal, therefore evil. They had no hierarchy, but an executive consisting of a bishop and two grades of Apostles. Besides the ordinary Bogomils there was a special order of the Perfect, who renounced all worldly possessions, marriage, animal food, and lived like hermits. They had no churches or images. They had a deathbed ceremony, without which one went to hell. They did not believe in purgatory.[190] But, as Prof. Bury remarks, it is doubtful if this is a true presentation of the Bogomil creed. Hardly any of their books of ritual survive, and all the accounts of them which have been preserved are written by their prosecutors. It is more probable that they were a monotheistic sect, believing in one God only, and rejecting the Trinity. This view is supported by the fact that at the time of the Turkish conquest such numbers of Bogomils became Muhamedans. It was not merely that they went over to the conqueror’s creed from motives of mere self-interest; there was really more similarity between that
