The medium is magical: a mesh mould lifted

old clothes, sails and rope fibres, an organic jumble

sinewed with chain and laid lines, then coated

with glue from boiled bones, to make off-white paper

that will take ink tannins. It’s a strong enough sizing

to carry still the marks from a dead bird’s feather

– a mortuary block and a figure half-rising,

Mantegna’s unnerving ‘Man on a Stone Slab’:

Lazarus perhaps, waking from a dead sleep, his bulk

borne on his left arm; his sheet’s ridges form

a foreshortened panorama. Gazing

amongst ghosts of pages and a crowd’s awkward shuffle

for perspective in the museum’s old Reading Room,

I feel my foot, as though willing a high-jump, lifting.
