he promises a secret heat

My hero bares his nerves along my wrist
That rules from wrist to shoulder,
Unpacks the head that, like a sleepy ghost,
Leans on my mortal ruler,
The proud spine spurning turn and twist.

And these poor nerves so wired to the skull
Ache on the lovelorn paper
I hug to love with my unruly scrawl
That utters all love hunger
And tells the page the empty ill.

My hero bares my side and sees his heart
Tread, like a naked Venus,
The beach of flesh, and wind her bloodred plait;
Stripping my loin of promise,
He promises a secret heat.

He holds the wire from the box of nerves
Praising the mortal error
Of birth and death, the two sad knaves of thieves,
And the hunger’s emperor;
He pulls the chain, the cistern moves.

[Dylan Thomas {1914-1953}, 'My Hero Bares His Nerves' from Collected Poems]
