Mary Sidney Herbert, Countess of Pembroke and sister to Sir Philip Sidney, is the most important woman writer of the Elizabethan era outside the royal family. This scholarly edition in two volumes is the first to include all her extant works: Volume I prints her three original poems, the disputed "Dolefull Lay of Clorinda," her translations from Petrarch, Mornay, and Garnier, and all her known letters. Volume II contains her metrical paraphrases of Psalms 44-150. The edition also provides a biographical introduction, discussion of her sources and methods of composition, textual annotation, and a detailed commentary.
