Some readers may have heard of Mary Sidney, accomplished poet and sister of the famous Sir Philip Sidney, but few will have heard of Aemilia Lanyer, the first woman in the seventeenth century to publish a book of original poetry, which offered a feminist take on the crucifixion, or Elizabeth Cary, who published the first original play by a woman, about the plight of the Jewish princess Mariam. These women had husbands and children to care for and little support for their art, yet against all odds they defined themselves as writers, finding rooms of their own where doors had been shut for centuries. Targoff flings those doors open, revealing the treasures left by these extraordinary women; in the process, she helps us see the Renaissance in a fresh light, creating a richer understanding of history and offering a much-needed female perspective on life in Shakespeare's day.
