did not succeed in making their escape, were sent in chains to Rome. But even these violent measures did little to diminish the strength of the Bogomiles in Bosnia, as in 1462 we are told that heresy was as powerful as ever in this country. The following year, when Bosnia was invaded by Muḥammad II, the Catholic king found himself deserted by his subjects: the keys of the principal fortress, the royal city of Bobovatz, were handed over to the Turks by the Bogomile governor; the other fortresses and towns hastened to follow this example, and within a week seventy cities passed into the hands of the Sultan, and Muḥammad II added Bosnia to the number of his numerous conquests. [663] From this time forth we hear but little of the Bogomiles; they seem to have willingly embraced Islam in large numbers immediately after the Turkish conquest, and the rest seem to have gradually followed later, while the Bosnian Roman Catholics emigrated into the neighbouring territories of Hungary and Austria. It has been supposed by some [664] that a large proportion of the Bogomiles, at least in the earlier period of the conquest, embraced Islam with the intention of returning to their faith when a favourable opportunity presented itself; as, being constantly persecuted they may have learnt to deny their faith for the time being; but that, when this favourable opportunity never arrived, this intention must have gradually been lost sight of and at length have been entirely forgotten by their descendants. Such a supposition is, however, a pure conjecture and has no direct evidence to support it. We may rather find the reason for the willingness of the Bogomiles to allow themselves to be merged in the general mass of the Musalman believers, in the numerous points of likeness between their peculiar beliefs and the tenets of Islam. They rejected the worship of the Virgin Mary, the institution of Baptism and every form of priesthood. [665] They abominated the cross as a religious symbol, and considered it idolatry to bow down before religious pictures and the images and relics of the saints. Their houses of prayer were very simple and unadorned, in contrast to the gaudily decorated Roman Catholic churches, and they shared the Muhammadan dislike of bells, which they styled “the devil’s trumpets.” They believed that Christ was not himself crucified but that some phantom was substituted in his place: in this respect agreeing partially with the teaching of the Qurʼān. [666] Their condemnation of wine and the general austerity of their mode of life and the stern severity of their outward demeanour would serve as further links to bind them to Islam, [667] for it was said of them: “You will see heretics quiet and peaceful as lambs without, silent, and wan with hypocritical fasting, who do not speak much nor laugh loud, who let their beard grow, and leave their person incompt.” [668] They prayed five times a day and five times a night,
