Four Seasons fill the measure of the year;
There are four seasons in the mind of man:
He has his lusty Spring, when fancy clear
Takes in all beauty with an easy span:
He has his Summer, when luxuriously
Spring’s honied cud of youthful thought he loves
 
To ruminate, and by such dreaming high
Is nearest unto heaven: quiet coves
His soul has […]

Season of mists and mellow fruitfulness!
Close bosom-friend of the maturing sun;
Conspiring with him how to load and bless
With fruit the vines that round the thatch-eaves run;
To bend with apples the mossed cottage-trees,
And fill all fruit with ripeness to the core;
To swell the gourd, and plump the hazel shells
With a sweet kernel; to set budding […]

My heart aches, and a drowsy numbness pains
My sense, as though of hemlock I had drunk,
Or emptied some dull opiate to the drains
One minute past, and Lethe-wards had sunk:
‘Tis not through envy of thy happy lot,
But being too happy in thy happiness,–
That thou, light-winged Dryad of the trees,
In some melodious plot
Of beechen green, and shadows […]

No, no! go not to Lethe, neither twist
Wolf’s-bane, tight-rooted, for its poisonous wine;
Nor suffer thy pale forehead to be kissed
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 […]

If by dull rhymes our English must be chain’d,
And, like Andromeda, the Sonnet sweet
Fetter’d, in spite of pained loveliness,
Let us find, if we must be constrain’d,
Sandals more interwoven and complete
To fit the naked foot of Poesy:
Let us inspect the Lyre, and weigh the stress
Of every chord, and see what may be gain’d
By ear industrious, and […]

 
When I have fears that I may cease to be
Before my pen has glean’d my teeming brain,
Before high-pilèd books, in charac’try,
Hold like full garners the full-ripen’d grain;
When I behold, upon the night’s starr’d face,
Huge cloudy symbols of a high romance,
And feel that I may never live to trace
Their shadows, with the magic hand of chance;
And […]

This famous sonnet was written by Keats in Joseph Severn’s copy of The Poetical Works of William Shakespeare opposite the poem ‘A Lover’s Complaint’.
Bright star! would I were steadfast as thou art—
Not in lone splendour hung aloft the night,
And watching, with eternal lids apart,
Like Nature’s patient sleepless Eremite,
The moving waters at their priestlike […]
