Sesquicentennial …

… Irish poet WB Yeats honoured with worldwide 150th birthday celebrations | Books | The Guardian. (Hat tip, Rus Bowden.)

Poet Bernard O’Donoghue, who is hosting the London event, said that Yeats was “a great public and private poet, and is almost unique in that way. There’s that great thing that TS Eliot said about him, that he was somebody without whom the history of his own time could not be understood.”
