Adam Daniel Veleslavin, born in 1545, studied at the University of Prague, and took his degrees there. He afterwards for some time lectured on history at that university, but after his marriage in 1576 to the daughter of the celebrated printer and publisher, George Melantrich, he became a partner in the business of his father-in-law. In this capacity he greatly furthered the development of Bohemian literature, and it is due to him that many books in that language were printed. Thoroughly acquainted with the art of writing his own language, he thoroughly supervised all the books that issued from his press, and, as Dr. Jireček writes, there is not one of them that doesn't show traces of having been corrected by him. He was occupied with lexicographic works in his own language, and with translations from other languages. Of his many works we may mention his _Politia Historica_, a translation, or rather adaptation, of the vast German work of Lauterbeck, which is entitled _Das Regentenbuch_, and his translation of the work of Ænæas Sylvius on Bohemia, which, in spite of its hostility to their country, greatly interested the Bohemians. The preface to this edition, Veleslavin's own work, contains an interesting account of the early historians of Bohemia. Of his mainly philological works, Veleslavin's _Silva Quadrilinguis_ and his _Nomenclator Quadrilinguis_ are the most important; both contain alphabetic vocabularies of the Bohemian, Latin, Greek, and German languages. The works issued from the Veleslavin press are so numerous that it seems certain that he had many collaborators in his critical work. Bernard of Hodijov and William Ostrovecký are specially mentioned as having acted as "sub-editors" to the works published by Veleslavin. Though he appears to have by no means been a man of genius, the influence of Veleslavin on Bohemian literature was very great, and it was an undoubted loss to the country that he died prematurely in 1599. The son of Adam Daniel, ADAM SAMUEL VELESLAVIN was born in 1592, only seven years before the death of his father. In his youth he was involved in the domestic quarrels and civil war which troubled Bohemia in the years 1618 to 1620. He was an enthusiastic adherent of the "Nationalist" party, to use a modern expression, and was obliged to fly from Bohemia after the fatal battle of the White Mountain. We have no record of him from the time that his exile began. His fortune was confiscated by the triumphant Catholics, and his printing-presses, which he had inherited from his father, were made over to the Jesuits. He had up to the downfall of Bohemian independence continued the editorial labours of his father, and had completed the publishing of several works begun by him. He also published in 1613 an edition of the Bible dedicated to the "defenders," that is, the leaders of the Protestant movement.
