WHAT are some literary devices used in this?

Seyton!—I am sick at heart,
When I behold—Seyton, I say!—This push
Will cheer me ever, or disseat me now.
I have lived long enough. My way of life
Is fallen into the sere, the yellow leaf,
And that which should accompany old age,
As honor, love, obedience, troops of friends,
I must not look to have, but, in their stead,
Curses, not loud but deep, mouth-honor, breath
Which the poor heart would fain deny and dare not.
Seyton!
