Mary Sidney Herbert, Countess of Pembroke (1561-1621) was born in 1561 in Worcestershire, England, toand Lady . served as Lord President of the Council in the Marches of Wales from 1559 to 1586, and then as Lord Deputy of Ireland from 1565 to 1571, and 1575 to 1578. Both the Sidney family and the Dudley family’s fortunes were dependent on the favor of the monarch. Lady Sidney served Queen Elizabeth for some time, which helped establish family favor and a good social position for Mary Sidney.
Mary Sidney had three brothers: Philip, Robert, and Thomas, and three sisters: Margaret, Elizabeth, and Ambrosia. She and her sisters received an excellent education: they learned scripture, classics, rhetoric, and a multitude of languages, including French, Italian, Latin, and possibly even Greek and Hebrew. They were also schooled in household medicine and administration, music, voice, lute, and needlework.
In 1575, Queen Elizabeth invited Sidney to court. In 1577, she became the third wife of, second Earl of Pembroke, becoming Countess of Pembroke at age 15. The pair had four children: William in 1580, Katherine in 1581, Anne in 1583, and Philip in 1584. After the deaths of her daughter Katherine, her father, mother, and brother Philip, all within two years, Sidney retreated to the Pembroke estates in Wiltshire for a period of mourning.
She returned to London in 1588, reentered public life, and began her career as a writer. Her early works included translations of essays written in Philip’s praise, completion of other writings by Philip, and the supervision of the publication of The Countess of Pembroke’s Arcadia (a text originally written by Philip for her). She also translated Petrarch’s Triumph of Death, and wrote at least three original poems: A Dialogue between Two Shepherds, Thenot and Piers, in Praise of Astrea; To the Angell Spirit of Sir; and Even Now that Care to Queen Elizabeth; perhaps also The Dolefull Lay of Clorinda.
Sidney modeled her writing after her brother’s, as well as. She wrote in styles “appropriate” for women of the time (elegy, encomium, and translation), to maintain traditional status while subtly transgressing the literary boundaries considered appropriate for women. Sidney never apologized for her writing, nor did she find it necessary to consistently reaffirm her gender.
Several of Sidney’s works were published during her lifetime. Two were English translations: A Discourse of Life and Death by Philippe de Mornay (originally in French), and A Tragedy by Robert Garnier (also originally in French). Both posited the importance of reason over emotion and public duty over private life, and were published in 1592. In 1595, “The Doleful Lay of Clorinda” was published in’s literary journal Astrophel. In 1602, “A Dialogue between Two Shepherds, Thenot and Piers, in Praise of Astrea,” was published in Francis Davison’s collection A Poetical Rhapsody.
Sidney also completed the translation from the Hebrew of the 150 Psalms, which her brother Philip had begun before his untimely death. Her Psalms were influential to later devotional poetry by George Herbert, Aemilia Lanyer, and John Donne. Donne himself said “We thy Sydnean Psalms shall celebrate.” A copy of the Psalms was presented to in 1599.composed metrical versions of Psalms 1–43; Mary Sidney completed the 150 Psalms. These translations into English verse have been praised for their word play, metrical complexity, use of rhetoric, use of metaphor, and scholarly and linguistic prowess. They were circulated widely at the time and recognized as her greatest literary achievement.
Sidney’s husband died in 1601, and she spent her years as a widow arranging marriages and positions at court for her children. She was celebrated as a writer during her lifetime, and is said to be the first English woman recognized as a poet. She died of smallpox on 25 September 1621 in London and is buried alongside her husband in Salisbury Cathedral.
