Alfred Tennyson, 1st Baron Tennyson, FRS (6 August 1809 – 6 October 1892), much better known as "Alfred, Lord Tennyson," was Poet Laureate of the United Kingdom during much of Queen Victoria's reign and remains one of the most popular poets in the English language.
Tennyson's poem "The Dying Swan" is a poetic evocation of the beauty of the supposed song and so full of detail as to imply that he had actually heard it:
The wild swan's death-hymn took the soul
Of that waste place with joy
Hidden in sorrow: at first to the ear
The warble was low, and full and clear; ...
But anon her awful jubilant voice,
With a music strange and manifold,
Flow’d forth on a carol free and bold;
As when a mighty people rejoice
With shawms, and with cymbals, and harps of gold...
