28 July 1664 – 3 August 1664

Came to see me Monsieur Zuylichen, Secretary to the Prince of Orange, an excellent Latin poet, a rare lutinist, with Monsieur Oudart.

To London; a concert of excellent musicians, especially one Mr. Berkenshaw, that rare artist, who invented a mathematical way of composure very extraordinary, true as to the exact rules of art, but without much harmony.
