Kathleen Jamie, "The Blue Boat"

How late the daylight edges
toward the northern night
as though journeying
in a blue boat, gilded in mussel shell

with, slung from its mast, a lantern
like our old idea of the soul

From Waterlight: Selected Poems. You can hear Jamie read from several of her poems at The Poetry Archive. The first third of Waterlight contains poems from The Tree House, a collection which won the 2004 Guardian Forward Prize for Poetry.
