Despite the fact that Percy Bysshe Shelley had been expelled from Oxford University in 1811 for publishing an anonymous pamphlet called The Necessity of Atheism, this elaborate memorial was erected to the poet there in 1893.

Shelly had drowned off the coast of Italy in 1822, at the age of 29.

Mother of this unfathomable world!
Favour my solemn song, for I have loved
Thee ever, and thee only; I have watched
Thy shadow, and the darkness of thy steps,
And my heart ever gazes on the depth
Of thy deep mysteries. I have made my bed
In charnels and on coffins, where black death
Keeps record of the trophies won from thee,
Hoping to still these obstinate questionings
Of thee and thine, by forcing some lone ghost
Thy messenger, to render up the tale
Of what we are. In lone and silent hours,
When night makes a weird sound of its own stillness,
Like an inspired and desperate alchymist
Staking his very life on some dark hope,
Have I mixed awful talk and asking looks
With my most innocent love, until strange tears
Uniting with those breathless kisses, made
Such magic as compels the charmèd night
To render up thy charge:…and, though ne’er yet
Thou hast unveiled thy inmost sanctuary,
Enough from incommunicable dream,
And twilight phantasms, and deep noon-day thought,
Has shone within me, that serenely now
And moveless, as a long-forgotten lyre
Suspended in the solitary dome
Of some mysterious and deserted fane,
I wait thy breath, Great Parent, that my strain
May modulate with murmurs of the air,
And motions of the forests and the sea,
And voice of living beings, and woven hymns
Of night and day, and the deep heart of man.

—Alastor; or, The Spirit of Solitude (1816)
