Analysis of Lines To A Dragon Fly

Life (priest and poet say) is but a dream;
I wish no happier one than to be laid
Beneath some cool syringa's scented shade
Or wavy willow, by the running stream,
Brimful of Moral, where the Dragon Fly
Wanders as careless and content as I.

Thanks for this fancy, insect king,
Of purple crest and filmy wing,
Who with indifference givest up
The water-lily's golden cup,
To come again and overlook
What I am writing in my book.
Believe me, most who read the line
Will read with hornier eyes than thine;
And yet their souls shall live for ever,
And thine drop dead into the river!
God pardon them, O insect king,
Who fancy so unjust a thing!
