Národní listy 10/1/1863 published news of a series of ‘Redouty’ [‘Redout’ or ‘redoute’ was a term, common to both Czech and German, for a masked ball]. The source related: ‘Redouty [Redouts]. On Sunday in the New Town Theatre will take place the first masked ball. In total there will be during this year’s Carnival 7 masked balls, specifically the first on Sunday and the last on Shrove Tuesday.’

The Theatre bill published in Bohemia 14/1/1863 noted: ‘Sunday 18th January takes place the second Masked Ball in the New Town Theatre.’ The same information was published later in Prager Morgenpost on 18/1/1863 and on 21/1/1863. The Theatre bills of Národní listy 15/1/1863 and 18/01/1863 announced (in Czech), the same news.’
