In 1665 the most significant event by far for England was the great plague of London, which took hold during the summer months and lasted until early 1666. The court moved to Salisbury in July 1665 and only returned to London the following February. The country was in the midst of the second Anglo-Dutch War, which began in March. (The first Anglo-Dutch War had been as long ago as 1652-1654, under the Commonwealth). An equally important event was the birth of a second daughter to the Duke and Duchess of York – Princess Anne would become Queen in 1702. Charles II’s third illegitimate son George Fitzroy, by Barbara Villiers Countess of Castlemaine, was born on 25 December 1665. He would later become Duke of Northumberland.

The diarist John Evelyn recorded a masque at court on 2 February. Samuel Pepys provided some additional details in his diary entry for the following day:

‘Then Mrs Pickering … did, at my Lady’s command, tell me the manner of the masquerade before the King and court the other day. Where six women (my Lady Castelmayne and Duchess of Monmouth being two of them) and six men (the Duke of Monmouth and Lord Arran and Monsieur Blancfort being three of them) in vizards, but most rich and antique dresses, did dance admirably, and most gloriously.’

There are no mentions of dancing in the theatres up to their closure, because of the plague, on 5 June 1665. They did not reopen until the autumn of 1666.

In France, Louis XIV’s mistress gave birth to two sons during 1665, one on 7 January (N.S.) and the other on 27 December (N.S.). Both babies died during 1666. The ballet de cour for 1665 was the Ballet de la Naissance de Vénus, in which the King’s sister-in-law Madame appeared as the goddess in the first Entrée with her husband as the Morning Star. She made her second appearance in the final Entrée as Roxane, with Louis XIV as Alexander the Great. The professional ballerina Mlle de Verpré appeared in the second Entrée of Part 2 as Daphne with a noble dancer, the Marquis de Beringuen, as Apollo. Another comédie-ballet by Molière and Lully, L’Amour Medecin, was given at Versailles on 15 September (N.S.) as an entertainment for a hunting party. It was later performed before the public at the Palais Royal in Paris.
