Hope is the thing with feathers

That perches in the soul,
And sings the tune--without the words,
And never stops at all,
'And sweetest in the gale is heard;
And sore must be the storm
That could abash the little bird
That kept so many warm.
'I've heard it in the chillest land,
And on the strangest sea;
Yet, never, in extremity,
It asked a crumb of me.'

The above poem by Emily Dickinson is an example of

A long simile
An extended metaphor
Exaggerated personification
Consonant alliteration
