What is Stonehenge?

What is Stonehenge? It is the roofless past;
Man's ruinous myth; his uninterred adoring
Of the unknown in sunrise cold and red;
His quest of stars that arch his doomed exploring.
And what is Time but shadows that were cast
By these storm-sculptured stones while centuries fled?
The stones remain; their stillness can outlast
The skies of history hurrying overhead.

Siegfried Sassoon (1886-1967)

Thanks to Nancy (Stones List) for first drawing my attention to this poem and to Moth for posting the 1786 illustration by Byrne and Medland of Stonehenge at -http://www.themodernantiquarian.com/img_fullsize/37125.jpg Both poem and illustration are now up on Megalithic Poems at http://megalithicpoems.blogspot.com/
