Though I am old with wandering

Through hollow lands and hilly lands,

I will find out where she has gone,

And kiss her lips and take her hands;

And walk among long dappled grass,

And pluck till time and times are done,

The silver apples of the moon,

The golden apples of the sun.

—“The Song of Wandering Aengus,”
William Butler Yeats

Which best describes an image of Aengus based on the first two lines of this stanza?

Aengus looks unhappy, because he has not found the girl.
Aengus looks tired and can no longer climb up and down.
Aengus looks old from walking everywhere.
Aengus looks worn out from climbing up and down mountains.
