“ At the private theatre attached to Brandenburg House the margravine produced in 1794 a comedy called the 'Yorkshire Ghost;' in 1799 a pantomime called 'Puss in Boots;' in 1805 a comedy called 'Love in a Convent,' and other works. For these plays the margravine composed the music. As she writes in her Memoirs, published in 1826: 'My taste for music and poetry and my style of imagination in writing, chastened by experience, were great sources of delight to me ... Our expenses were enormous.' The margravine often took part in the performances at Brandenburg House. ”
