The recent discovery of this first draft of one of the Bard's most famous sonnets may, or may not, shed further light on the identity of the Dark Lady...

Sonnet 18

Shall I compare thee to a Brussel sprout?
Thou art more tasty and more versatile.
Rough winds may shake those round about,
But summer sees you firm, with rounded smile.
Sometimes, as you stand rooted in the soil,
Whitefly and pigeons may assault your leaves,
And, spite of the gardener's eternal toil,
Your heart lies open to nocturnal thieves.
But know there is just one true end for you:
Your destiny is the simmering pot,
As part of a casserole, soup or stew,
Or a nourishing side dish, piping hot.
So long a source of vitamin 'C',
Cabbage, your iron gives long life to me.
