John Keats
Ode on Melancholy
No, no! go not to Lethe, neither twist
Wolf's-bane, tight-rooted, for its poisonous wine;
Nor suffer thy pale forehead to be kist
By nightshade, ruby grape of Proserpine;
Make not your rosary of yew-berries
Nor let the beetle, nor the death-moth be
Your mournful Psyche, nor the downy owl
A partner in your sorrow's mysteries;
For shade to shade will come too drowsily
And drown the wakeful anguish of the soul

But when the melancholy fit shall fall
Sudden from heaven like a weeping cloud
That fosters the droop-headed flowers all
And hides the green hill in an April shroud;
Then glut thy sorrow on a morning rose
Or on the rainbow of the salt sand-wave
Or on the wealth of globèd peonies;
Or if thy mistress some rich anger shows
Emprison her soft hand, and let her rave
And feed deep, deep upon her peerless eyes

She dwells with Beauty—Beauty that must die;
And Joy, whose hand is ever at his lips
Bidding adieu; and aching Pleasure nigh
Turning to poison while the bee-mouth sips:
Ay, in the very temple of Delight
Veil'd Melancholy has her sovran shrine
Though seen of none save him whose strenuous tongue
Can burst Joy's grape against his palate fine;
His soul shall taste the sadness of her might
And be among her cloudy trophies hung
