England continued to be involved in the second Anglo-Dutch War, with sea battles in June and July and a raid on Holland in August 1666, but the most significant event of the year (as destructive of property as the plague of the previous year had been of life) was the great fire of London in early September.

The blaze left much of the city in ruins and it would take some years before life returned to normal. London’s theatres, in what was becoming the ‘West End’ were too far from the city itself to be directly affected. They reopened in December 1666 following their 18-month closure because of the plague. With so few performances in 1666, it is hardly surprising that there was no mention of dancing.
In France, the Queen Mother Anne of Austria died on 20 January 1666 (N.S.). Louise de la Vallière gave birth to Louis XIV’s daughter on 2 October (N.S.). She was known as Marie Anne de Bourbon and then, after she was legitimised, as Mlle de Blois. The first danced entertainment of the year preceded the death of the Queen Mother. The mascarade Le Triomphe de Bacchus was performed at the Palais Royal on 9 January 1666 (N.S.) with a cast entirely of male professional dancers. Pierre Beauchamps danced Bacchus. That year’s ballet de cour was delayed until mourning for the Queen Mother was over. The Ballet des Muses was first given at St Germain-en-Laye on 2 December 1666 (N.S.) and continued to be performed until February 1667. Louis XIV renewed his dance partnership with his sister-in-law Madame, who was indisputably the ballet’s leading female dancer. They appeared together in the 4th Entrée as a Berger and Bergère, in the 6th Entrée as an Espagnol and Espagnolle and in the 14th and final Entrée as a Maure and Mauresque. In addition, Madame appeared among the ladies of the court as the leading Pieride in the 11th Entrée. The King also danced as Cyrus in the 8th Entrée and as a Nymphe in the 12th Entrée. The latter marked his last appearance in a female role.
