Dalibor is based on events that took place in the 15th century: having led a peasant revolt, the Knight Dalibor of Kozojedy was imprisoned, by order of King Vladislav II of Bohemia, in a tower in Prague Castle that still bears the name “Daliborka” to this day. Legend has it that he learned to play the violin while he was incarcerated, and that the people passing by the tower would be moved on hearing his music.
