Mary Beale (1633-1699) (attributed to) - Portrait of an Unknown Lady in Blue - 266428 - National Trust

Mary Beale (1633–1699) was an English portrait painter. She was part of a small band of female professional artists working in London. Beale became the main financial provider for her family through her professional work – a career she maintained from 1670/71 to the 1690s. Beale was also a writer, whose prose Discourse on Friendship of 1666 presents scholarly, uniquely female take on the subject.
