Explanation:
"The Wild Swans at Coole" set in Coole Park Ireland is William Buttler Yeats' (1865–1939) lyrical poem written before the end of the World War I (1916-17) and during Irish struggle for freedom from the Britain.
The speaker/poet in the start of the poem says that nineteen years ago when he visited the same park, all the swans suddenly flew away before he could finish counting them.
<em>"I saw, before I had well finished,
</em>
<em>All suddenly mount
</em>
<em>And scatter wheeling in great broken rings
</em>
<em>Upon their clamorous wings"</em>
However near the end of the poem he says that now, the swan did not fly, but just keep drifting on the still water,
<em>"But now they drift on the still water,
</em>
<em>Mysterious, beautiful;"</em>
