Mary Pix was born in 1666 (the year of the Great Fire of London), had her first big London successes in 1696, and went on to write an estimated 13 plays (both tragedies and comedies) and one novel, despite the opposition of what we might as well call the patriarchy. A retitled production of her 1700 script The Beau Defeated opens this month at Stratford-upon-Avon.
