Who are these coming to the sacrifice?
To what green altar, O mysterious priest,
Lead’st thou that heifer lowing at the skies,
And all her silken flanks with garlands drest?
What little town by river or sea shore,
Or mountain-built with peaceful citadel,
Is emptied of this folk, this pious morn?
And, little town, thy streets for evermore
Will silent be; and not a soul to tell
Why thou art desolate, can e’er return.
Keats – Ode On A Grecian Urn
