The German-language newspaper Tagesbote aus Böhmen 23/1/1858 related news attributed to Prager Zeitung that ‘In the Apartments of Their Majesties the Emperor Ferdinand and the Empress Maria Anna took place yesterday a thé dansant. The glittering party, which went on past 12 midnight, included His Royal Highness the Archduke Jospeh, His Eminence the Cardinal-Archbishop von Schwarzenberg, His Excellency the Governor Baron von Mecséry, the flower of the high nobility, the highest of the Civil and Military authorities and representatives of the Royal Officer Corps.’ No details of the musical content of the occasion were noted by the report.

‘Thé dansant’ translates obviously as a ‘tea dance’, although the occasion was probably a a general dance soirée.
