Which type of symbol does this poem by William Butler Yeats use?
The Wild Swans at Coole
… Upon the brimming water among the stones are nine-and-fifty swans
The nineteenth autumn has come upon me
Since I first made my count:
I saw, before I had well finished,
All suddenly mount
And scatter wheeling in great broken rings
Upon their clamorous wings …
But now they drift on the still water.
Mysterious, beautiful:
Among what rushes will they build,
By what lake’s edge or pool
Delight men’s eyes when I awake some day
To find they have flown away?
