Not a very strong refraction..

At the Piano
Thomas Hardy, 1840 - 1928
A Woman was playing,
A man looking on;
And the mould of her face,
And her neck, and her hair,
Which the rays fell upon
Of the two candles there,
Sent him mentally straying
In some fancy-place
Where pain had no trace.
A cowled Apparition
Came pushing between;
And her notes seemed to sigh;
And the lights to burn pale,
As a spell numbed the scene.
But the maid saw no bale,
And the man no monition;
And Time laughed awry,
And the Phantom hid nigh.
