On 17 April 1817, Keats settled in a room at Carisbrooke, where he started a letter to Reynolds, and wrote a sonnet ‘On the Sea’
On the Sea
It keeps eternal whisperings around
Desolate shores, and with its mighty swell
Gluts twice ten thousand caverns, till the spell
Of Hecate leaves them their old shadowy sound.
Often ’tis in such gentle temper found,
That scarcely will the very smallest shell
Be moved for days from where it sometime fell,
When last the winds of heaven were unbound.
Oh ye! who have your eye-balls vex’d and tired,
Feast them upon the wideness of the Sea;
Oh ye! whose ears are dinn’d with uproar rude,
Or fed too much with cloying melody, —
Sit ye near some old cavern’s mouth and brood,
Until ye start, as if the sea-nymphs quired!
John Keats: Sonnet written 17 April 1817.
