Michael Robartes and the Dancer.

"Turning and turning in the widening gyre,

The falcon cannot hear the falconer"

First edition, first impression, one of 400 copies printed and now very scarce. The significant English composer and co-founder of the original Glastonbury Festivals Rutland Boughton's copy, with his ownership inscription "R. Boughton, Glastonbury" to first blank and matching purple ink stamp to the title page.

Rutland Boughton (1878-1960) remains best known for "The Immortal Hour", an operatic reworking of Celtic Revival author Fiona Macleod (pseudonym of William Sharp, 1855-1905), which premiered at the inaugural Glastonbury Festival in 1914 and had a hugely successful London run between 1922 and 1923. Elgar described it as "a work of genius".

Michael Robartes and the Dancer is an important Yeats collection, notable for its mythical imagining of contemporary politics. Famous poems include "Easter, 1916" ("All changed, changed utterly: / a terrible beauty is born") and perhaps Yeats's most famous poem, "The Second Coming", with its unforgettable opening, "Turning and turning in the widening gyre / The falcon cannot hear the falconer; / Things fall apart; the centre cannot hold; / Mere anarchy is loosed upon the world...", and closing lines, "what rough beast, its hour come round at last / Slouches towards Bethlehem to be born?"
