Dorothy Sidney Countess of Sunderland

While Dorothy, Countess of Sunderland , has been known historically as the Sacharissa of Edmund Waller 's poetry, she was also a respected and memorable letter writer. Most of her surviving letters date from her later life, and provide her commentary on the political infighting and social atmosphere of the court of Charles II , as well as information on her own family and friends. In 1666 a friend referred to her writing as that of the most eloquent pen in England.
