Read the passage from "Ode on a Grecian Urn." 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.

The tone changes from curious to lonely.
The tone changes from admiring to bored.
The tone changes from irritated to peaceful.
The tone changes from unhappy to reassured.
