Individual Details

Birth

was one of the first English women to achieve a major reputation for her literary works, poetry, poetic translations and literary patronage.
Mary was mainly brought up at Ludlow Castle, the seat of the President of the Welsh Marches, a role her father held until 1586. Like her brother, Sir Philip Sidney, she received a Calvinist education, which included classics, French, Italian, Hebrew, music and needlework.
Following the death of her youngest sister, Ambrosia Sidney in 1575, Mary was summoned to London to attend Queen Elizabeth I. In 1577, her mother's brother, Robert Dudley, 1st Earl of Leicester, helped Sir Henry Sidney to arrange her marriage to their close ally, Henry Herbert, 2nd Earl of Pembroke, then in his mid-forties. As Countess of Pembroke, Mary was responsible for a number of estates including Ramsbury, Ivychurch Priory (Alderbury, Wilts), Wilton House and Baynard's Castle, London where it is known that they entertained Queen Elizabeth to dinner. She bore Pembroke four children, the first of whom, William Herbert, 3rd Earl of Pembroke (1580–1630) may be the young man described in Shakespear's Sonnets. Their other surviving child, Philip Herbert, 4th Earl of Pembroke, became the 4th Earl of Pembroke on his brother's death in 1630. These sons are the "Incomparable Pair" to whom William Shakespeare's First Folio is dedicated. At different times, both were patrons of the King's Men. Her daughter, Dorothy (born 1586 - died 1615 in Gravesend, Kent, ENG) married Sir Richard Devereaux Gilliam (born 1583 - died 1651 in Norfolk, Virginia, USA), the elder son of Walter, Viscount Hereford of Herefordshire, England.

Marriage

Mary was the third wife of Henry Herbert.
Mary Sidney was highly educated in the humanist tradition. In the 16th century, noblewomen were educated to enable them to have a good understanding of theological issues and the classics, to interpret original texts and, if necessary, to deputize for their husbands. Her education enabled her to translate Petrarch's "Triumph of Death" and several other European works. She had a keen interest in chemistry and set up a chemistry laboratory at Wilton House, run by Walter Raleigh's half-brother. She also had an interest in making medicines.
She was interested in musical codes and invisible ink. She turned Wilton into a "paradise for poets", known as "The Walton Circle" which included Edmund Spense, Michael Drayton, Sir John Davies and Samuel Daniel, a salon-type literary group sustained by the Countess's hospitality. Her aim shared with her brother Sir Philip Sidney was to strengthen and classicise the English language and to support "true" religion, which, in their view, combined Calvinism, the principles of Castiglione, and acts of charity. She was herself a Calvinist theologian and her public persona (at least) was pious, virtuous and learned. She was regarded as a muse by Samuel Daniel in his poem "Delia" (an anagram for ideal).
Mary Sidney was said to inspire creativity in all those around her, including her circle, relatives and servants. Philip Sidney wrote much of his "Arcadia" for her, and in her presence, at Wilton House. Before his death, Philip Sidney was engaged in preparing a new English version of the Book of Psalms (because the translations under Edward VI were deficient). He had completed 43 of the 150 Psalms at the time of his death during a military campaign against the Spanish in the Netherlands in 1586. She finished Philip's translation of the Psalms, composing Psalms 44-150 in a dazzling array of verse forms, using the 1560 Geneva Bible and commentaries by John Calvin and Theodoe Beza. As a competent theologian, she was unafraid to disagree with Calvin on minor points. A copy of the completed Psalms was presented to Elizabeth I of England in 1599. This work is usually referred to as "The Sidney Psalms" or "The Sidneian Psalms" and is regarded as an important influence on the development of English poetry in the late 16th and early 17th century. John Donne wrote a poem celebrating them. The Psalms were drawn from previous English translations rather than original Hebrew texts and are therefore properly called "metaphrases" rather than translations. Like Philip's, Mary Sidney's versions display a vivid imagination and vigorous phrasing. Mary also took on the task of editing and publishing Philip Sidney's "Arcadia" as The Counesse of Pembroke;s Arcadia, one of the most widely read books in English for the next 200 years.
Mary's husband died in 1600 leaving her, John Aubrey reported, with less financial support than she might have expected (through views on its adequacy vary). Her husband's will required that she did not remarry. Thereafter, her time was spent managing Wilton and the other Pembroke estates, on behalf of her son, Wiliam Herbert, 3rd Earl of Pembroke, who entirely took over her role of literary patronage. After James I of England visited her at Wilton in 1603 and was entertained by Shakespeare's company "The King's Men", Mary moved out of Wilton as Dowager Countess and rented homes in London. Though it is certain that the King's Men attended Wilton, whether William Shakespeare was with them remains unconfirmed. However, it is reported that there was at Wilton at one time, a letter in which the Mary Sidney urged her son to attend Wilton, as "we have the man Shakespeare with us".
From 1609 to 1615 she was probably based at Crosby Hall, London, now relocated as a private residence relocated to Chelsea, London. She may have secretly married her doctor, Sir Matthew Lister, and she travelled to Spa on the Continent with him, where she relaxed by shooting pistols and played cards. She built a Bedfordshire hunting lodge with fine vistas, Houghton House, now ruined near Milton Keynes, which John Bunyan refers to in his works, as the "House Beautiful".
