") and a destination (the "green altar"). But all he can think is that the town will forever be deserted: if these people have left their origin, they will never return to it. In this sense he confronts head-on the limits of static art; if it is impossible to learn from the urn the whos and wheres of the "real story" in the first stanza, it is impossible ever to know the origin and the destination of the figures on the urn in the fourth.

The third attempt fails simply because there is nothing more to say--once the speaker confronts the silence and eternal emptiness of the little town, he has reached the limit of static art; on this subject, at least, there is nothing more the urn can tell him. In the final stanza, the speaker presents the conclusions drawn from his three attempts to engage with the urn.
