Famous quotes containing the word john:
“And that enquiring man John Synge comes next,
That dying chose the living world for text
And never could have rested in the tomb
But that, long travelling, he had come
Towards nightfall upon certain set apart
In a most desolate stony place....”
—William Butler Yeats (1865–1939)
