The Song of Wandering Aengus

 
I went out to the hazel wood,
Because a fire was in my head,
And cut and peeled a hazel wand,
And hooked a berry to a thread;
And when white moths were on the wing,
And moth-like stars were flickering out,
I dropped the berry in a stream
And caught a little silver trout.
When I had laid it on the floor
I went to blow the fire a-flame,
But something rustled on the floor,
And someone called me by my name:
It had become a glimmering girl
With apple blossom in her hair
Who called me by my name and ran
And faded through the brightening air.
Though I am old with wandering
Through hollow lands and hilly lands,
I will find out where she has gone,
And kiss her lips and take her hands;
And walk among long dappled grass,
And pluck till time and times are done,
The silver apples of the moon,
The golden apples of the sun.

W.B. Yeats (1865–1939)
The Wind Among the Reeds. 1899.

He was said to have four birds symbolizing kisses flying about his head (whence, it is believed, the xxxx's symbolizing kisses at the end of lovers' letters come from . His parents were the Dagda and Boann. He was said to have lived at Newgrange by the river Boyne.
