Budova then tells us how he became a member of the numerous embassy that accompanied the ambassador John of Zinzendorf to Constantinople. While most of his companions, after a short stay at Constantinople, continued their travels to "Jerusalem, Damascus, Babylon, Arabia, and Persia," Budova was detained there, for he had accepted the position of _hofmistr_ (master of the ceremonies) to the ambassador. "I then," Budova writes, "decided to make inquiries as to what the religion, or rather irreligion, of the Turks really was, and, as it were, to outline and depict for others that Turkish Antichrist with his fables and other frauds. It was of great assistance to me that I had with me a copy of the _Alkoran_ (Koran), which in Spain had been translated from the ancient Arabic, such as it was at the time of Mahomet, into the Latin speech. This book was then, at the time of Luther, about the year 1550, printed with a preface by Philip Melanchthon. I, possessing this work, often entered into discussions, not only with the Turks, but also with the renegades--that means those who have fallen from the Christian faith, and of such there are here not hundreds but thousands. The result was that they themselves were surprised, and had to laugh at those most foolish fables (of the Koran), which are sillier than anything that has been taught by any heathens since the beginning of the world. Then, overcome by their consciences, they arrived at this conclusion--that they did not believe in God and in eternal life, but that, in accordance with Epicurus and the Sadduceans, they considered every religion as a political institution, and favoured such religious doctrines as were convenient to their bodily welfare, and contributed to their glory and advantage in the world. And as at Constantinople I saw all this with my eyes, that 'Gog and Magog', which in Bohemian can be described as the secret building, the extraordinary edifice composed of parts of the New and Old Testament, in which that Satan (_i.e._ the Sultan) endeavours to hide himself with his _Alkoran_--as I talked much on these subjects with Turks and renegades, that is, men who have abandoned the Christian faith, therefore am I better able to write on these subjects than those who only write what they have heard at second-hand." The _Anti-Alkoran_ is divided into three parts. The first consists of copious extracts from the edition of the Koran mentioned in the preface; the second contains a refutation of the Mohammedan creed. The third part, scarcely connected with the others, consists of nine small treatises, which prove that the inclination to mysticism, that proved so harmful to Komenský and many brethren, existed in Budova's mind also, and that, like so many of his contemporaries, he was given to the study of astrology.
