The sundial stands in a patch of grass:
that is a wabe -- as C.S.Lewis
assigned the name, but it is not
the wabe that makes the dial into
a sundial. The plinth of this one carved
with summer sun and autumn leaves
and with today's bleak winter trees
but mere plinth is not sundial. The gnomon,
all rough with verdigris except
where hands have worn it back to smooth
and bronze, also its leaching copper
has stained the dial, but though this wedge
and dial are necessary for
a sundial, they are not sufficient:
another thing's required. There's rain
upon the sundial all today,
the sky of grey has left my time
quite undefined: a dial undone.
