According to Dr. Jireček, the total sum of the works of Blahoslav amounts to twenty-eight; many of them, however, including his most important work, have been lost. His controversial writings on theology, as was then usual, mostly took the form of letters. Such writings are the letters to Brother Zachary, to Martin of Žátec (Saaz), to the Lord Marshal Berthold of Lípa, &c. Like Augusta, Blahoslav was a great writer of hymns, many of which are preserved in the _Kancionali_ or hymn-books of the Unity. The composition of these hymns no doubt induced Blahoslav to write the curious treatise entitled _Music_, or, to give the full name as prefixed to the second edition of Blahoslav's book, "Music, that is, a small book containing the information necessary for singers. Written in the Bohemian language on the wish of several good friends, and first printed in the year of the Lord 1558 at Olmütz; now carefully corrected and reprinted; rules and instructions necessary to chanters and composers of hymns are added." In the preface to this quaint work Blahoslav writes: "A branch of pride, and not the least one, consists in the desire to be known to many, to be considered witty and sensible, and to be esteemed in consequence. The desire to obtain distinction by one's virtues and other similar things is indeed praiseworthy. Yet it is senseless to undertake too difficult a work and strive with much effort for an object as vain as the steam of smoke. There are many, too, who might be compared to that Herostratus, who, wishing to obtain great fame, burnt down the great Temple of Diana at the risk of his life.... Those only will I mention who, in our days, publish books in the Bohemian language, wishing thus to obtain great fame for themselves; some who wish to help their neighbours as much as they can, from sincere love and in a beseeming manner, I do not allude to; on the contrary, I praise their pious undertakings and holy labour; but many are guided and incited by that branch of pride which I have mentioned above, which drives them to attempt that also which is beyond their power. Thus they do what they are unfit to do, thinking it sufficient that they have done it. But how? that they don't think of or care. Many out of good Latin or German books make bad Bohemian ones, serving no other purpose than that the noble Bohemian language, already somewhat spoilt, should become yet more corrupted. This will perhaps bring matters to that point that the Bohemians will become unable to speak Bohemian correctly and rightly to understand their language and its peculiarities. Thus did it happen to the Italians, who had so amended their language that when the old Italians--that is, the Latinists, Cicero and the others--came to them, they could not understand them. And what happens with regard to translations from other languages, that happens also with regard to the composition and publication of various little songs, particularly when those who
