<P> During 1885, Yeats was involved in the formation of the Dublin Hermetic Order . The society held its first meeting on 16 June, with Yeats acting as its chairman . The same year, the Dublin Theosophical lodge was opened in conjunction with Brahmin Mohini Chatterjee, who travelled from the Theosophical Society in London to lecture . Yeats attended his first séance the following year . He later became heavily involved with the Theosophy and with hermeticism, particularly with the eclectic Rosicrucianism of the Hermetic Order of the Golden Dawn . During séances held from 1912, a spirit calling itself "Leo Africanus" apparently claimed it was Yeats's Daemon or anti-self, inspiring some of the speculations in Per Amica Silentia Lunae . He was admitted into the Golden Dawn in March 1890 and took the magical motto Daemon est Deus inversus--translated as' Devil is God inverted' . He was an active recruiter for the sect's Isis - Urania Temple, and brought in his uncle George Pollexfen, Maud Gonne, and Florence Farr . Although he reserved a distaste for abstract and dogmatic religions founded around personality cults, he was attracted to the type of people he met at the Golden Dawn . He was involved in the Order's power struggles, both with Farr and Macgregor Mathers, and was involved when Mathers sent Aleister Crowley to repossess Golden Dawn paraphernalia during the "Battle of Blythe Road". After the Golden Dawn ceased and splintered into various offshoots, Yeats remained with the Stella Matutina until 1921 . </P> <P> In 1889, Yeats met Maud Gonne, a 23 - year - old English heiress and ardent Irish Nationalist . She was eighteen months younger than Yeats and later claimed she met the poet as a "paint - stained art student ." Gonne admired "The Island of Statues" and sought out his acquaintance . Yeats began an obsessive infatuation, and she had a significant and lasting effect on his poetry and his life thereafter . In later years he admitted, "it seems to me that she (Gonne) brought into my life those days--for as yet I saw only what lay upon the surface--the middle of the tint, a sound as of a Burmese gong, an over-powering tumult that had yet many pleasant secondary notes ." Yeats's love was unrequited, in part due to his reluctance to participate in her nationalist activism . </P> <P> In 1891 he visited Gonne in Ireland and proposed marriage, but was rejected . He later admitted that from that point "the troubling of my life began". Yeats proposed to Gonne three more times: in 1899, 1900 and 1901 . She refused each proposal, and in 1903, to his dismay, married the Irish nationalist Major John MacBride . His only other love affair during this period was with Olivia Shakespear, whom he first met in 1894, and parted from in 1897 . </P> <P> Yeats derided MacBride in letters and in poetry . He was horrified by Gonne's marriage, at losing his muse to another man; in addition, her conversion to Catholicism before marriage offended him, although he was Protestant / agnostic . He worried his muse would come under the influence of the priests and do their bidding . </P>
