A symbol is indeed the only possible expression of some invisible essence, a transparent lamp about a spiritual flame; while allegory is one of many possible representations of an embodied thing, or familiar principle, and belongs to fancy and not to imagination: the one is a revelation, the other an amusement.
I have desired, like every artist, to create a little world out of the beautiful, pleasant, and significant things of this marred and clumsy world, and to show in a vision something of the face of Ireland to any of my own people who would look where I bid them. I have therefore written down accurately and candidly much that I have heard and seen, and, except by way of commentary, nothing that I have merely imagined.
Out-worn heart, in a time out-worn,
Come clear of the nets of wrong and right;
Laugh, heart, again in the grey twilight,
Sigh, heart, again in the dew of the morn.
And if joy were not on the earth,
There were an end of change and birth,
And Earth and Heaven and Hell would die,
And in some gloomy barrow lie
Folded like a frozen fly.
The soldier takes pride in saluting his Captain,
The devotee proffers a knee to his Lord,
Some back a mare thrown from a thoroughbred,
Troy backed its Helen, Troy died and adored;
Great nations blossom above,
A slave bows down to a slave.
You ask what I have found and far and wide I go,
Nothing but Cromwell's house and Cromwell's murderous crew,
The lovers and the dancers are beaten into the clay,
And the tall men and the swordsmen and the horsemen where are they?
Through winter-time we call on spring,
And through the spring on summer call,
And when the abounding hedges ring
Declare that winter's best of all:
And after that there's nothing good
Because the spring time has not come-
Not know that what disturbs our blood
Is but its longing for the tomb.
