I See my life go drifting like a river
From change to change; I have been many things --
A green drop in the surge, a gleam of light
Upon a sword, a fir-tree on a hill,
An old slave grinding at a heavy quern,
A king sitting upon a chair of gold --
And all these things were wonderful and great;
But now I have grown nothing, knowing all.
Ah! Druid, Druid, how great webs of sorrow
Lay hidden in the small slate-coloured thing!
- - W.B. Yeats, 'Fergus and the Druid,' 1892
