with literary authors. She became friendly with Thomas MacGreevy, whom she invited for tea, later writing to him, "WBY has given me the new edition of Reveries and the Veil, & I am re-reading it all. It is very beautifully done. He was about 29 when I first knew him". McGreevy told Yeats that Olivia was "always a symbol of elegance, a kind of gold and ivory image". Harwood writes of her, "Olivia Shakespear was avant-garde in literature, agnostic in religion, and conservative in politics, at least later in life". Olivia's correspondence with Pound continued throughout the 1920s and 1930s, when she acted in part as his agent in London. In 1924, at Pound's request, she welcomed George Antheil into her social circle, procured artwork and books that were sent on to Dorothy and Ezra in Rapallo, and mediated in a dispute between Pound and Lewis. She was uninterested in Pound's politics and economic views and particularly disliked his later Cantos. After her husband's death, Olivia's income was sufficient to support a comfortable lifestyle. During the 1920s and 1930s she gradually increased Dorothy's income (which was also increased by various family bequests), and in the 1930s she made investments in Dorothy's name, sending the proceeds to Dorothy and Pound. In a very real sense, according to Harwood, Olivia Shakespear is the "unsung heroine" of the modernist period, because much of the money Ezra Pound generously used to support struggling writers such as T. S. Eliot and James Joyce came from her. Olivia died of complications brought on by gall bladder disease on 3 October 1938. The day before her death she wrote in a letter to Dorothy: "On Monday I was taken suddenly ill with gall bladder trouble—awful pain—sent for Doctor Barnes—he gave me dope & an injection and pain gradually went ... He says I am going on all right, but of course I feel rather a wreck". She died the following day of a heart attack. John Unterecker believes Olivia's death shattered Yeats, who died only months later, because she added warmth to his life. Yeats wrote of her death:Olivia Shakespear has died suddenly. For more than forty years she has been the centre of my life in London and during all that time we have never had a quarrel, sadness sometimes but never a difference. When I first met her she was in her late twenties but
