When did the leader of the Wilton Circle die?
Mary Sidney Mary Herbert, Countess of Pembroke (née Sidney; 27 October 1561 – 25 September 1621) was one of the first English women to achieve a major reputation for her poetry and literary patronage. By the age of 39, she was listed with her brother Philip Sidney, Edmund Spenser, and William Shakespeare, as one of the notable authors of her time in the verse miscellany by John Bodenham, "Belvedere". The influence of her "Antonius" is widely recognized: it stimulated a revived interest in the soliloquy based on classical models, and was a likely source (among others) for both the 1594 closet drama "Cleopatra" by Samuel Daniel and Shakespeare’s "Antony and Cleopatra" (1607). Sidney was also known for her translation of Petrarch's "Triumph of Death", but it is her lyric translation of the Psalms that has secured her poetic reputation.
Albert Spencer, 7th Earl Spencer Albert Edward John Spencer, 7th Earl Spencer {'1': ", '2': ", '3': ", '4': "} , (23 May 1892 – 9 June 1975), styled The Honourable Albert Spencer until 1910 and as Viscount Althorp from 1910 to 1922, and known less formally as "Jack" Spencer, was a British peer. He was the paternal grandfather of Diana Spencer, who was just under 14 years old at the time of his death. Diana would go on to marry Charles, Prince of Wales, heir to the British throne, six years later.
