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?

–“Ode on a Grecian Urn,”
John Keats

What does the word mysterious suggest about the image on the urn?

The image is decorative.
The image is frightening.
The image is intriguing.
The image is brightly colored.
*ANSWER C*

The image is intriguing.

Explanation:

John Keats' poem "Ode on a Grecian Urn" revolves around an unnamed speaker who is observing an old, Grecian urn decorated with images of ancient rural Grecian life. And through the image that he saw, the speaker expresses his admiration at the perfect, beautiful image on the urn, though captured inanimate.

In the given lines from the fourth stanza, the speaker addresses the urn, asking "who are these coming to the sacrifice?", seemingly addressing the "mysterious priest" in the picture. This use of the word "mysterious" suggests that the image that is shown depicted on the urn is intriguing to the speaker and is interesting to him.

Thus, the correct answer is the third option.
