William Watson - The Eternal Search

MY little maiden two years old, just able
To tower full half a head above the table,
With inquisition keen must needs explore
Whatever in my dwelling hath a door,
Whatever is behind a curtain hid,
Or lurks, a rich enigma, 'neath a lid.
So soon is the supreme desire confessed,
To probe the unknown! So soon begins the quest,
That never ends until asunder fall
The locks and bolts of the Last Door of All.

William Watson
