The Daliborka Tower is very famous in popular legends. It is said to have received its present name from Dalibor of Kozojed, a knight who was imprisoned here during the reign of Vladislav II. The serfs of a neighbouring knight, Adam of Ploskov, had been driven to revolt by the cruelty of their lord, and Dalibor availed himself of this opportunity for seizing Ploskov's estates. He was, therefore, imprisoned in the tower to which he has given his name, and afterwards decapitated. This somewhat sordid event became the nucleus of legends created by the imaginative Bohemian people. It was said that Dalibor, after spending some years in foreign lands, had returned to Bohemia, and there witnessed the cruelties from which the Bohemian peasants, formerly free men, suffered; for bondage, entirely alien to the ancient customs of Bohemia, was only established there in 1487. Under the influence of Rozvod, an old man who remembered the days of Zizka, Dalibor incited the peasants to rise against their lords. The revolt was rapidly suppressed, and Dalibor imprisoned in the tower on the Hradcany Hill. It was said that while imprisoned he learnt to play the violin to solace his solitude, and that his music attracted crowds to the tower. The great Bohemian musician Smetana has given the name of 'Dalibor' to one of his operas, and Dalibor is also the hero of one of the books of the talented Bohemian novelist Wenceslas Vlcek. Among the later prisoners in the Daliborka were several alchemists whom Rudolph II. called to his court, but who failed to fulfil the promises they had made. The astronomer Francis Tennagel, an assistant of Tycho Brahe, was also a prisoner in the Daliborka during Rudolph's reign. We obtain the best view of the four towers, and indeed of the Hradcany generally, if we cross the Stag's Ditch and proceed to the Royal gardens, in which is the Belvedere villa. Ferdinand I. caused it to be built for his wife Anna. It is a fine specimen of the Italian Renaissance, Ferdinand's favourite form of architecture, and was built by the Italian, John de Spatio. In the interior of the building there are some frescoes of the earlier part of the nineteenth century representing scenes from Bohemian history. It is characteristic of the period that the Hussite Wars, the period of Bohemia's greatness, are entirely excluded. As a proof that the present Emperor of Austria from his earliest youth possessed the sagacity and clearness of mind which is now recognised by the whole world, it may be mentioned that when, as a young Archduke, he visited these frescoes, he is reported to have said: 'It is impossible even to conceive a history of Bohemia from which the Hussite Wars are excluded.' Close to the Belvedere is a fountain, which has rightly been called 'one of the finest Renaissance fountains north of the Alps.' The design is by Tertio of Bergamo, and the work was carried out by Jarus, an artist of Prague.
