Climbing My Grandfather

I decide to do it free, without a rope or net.
First, the old brogues, dusty and cracked;
an easy scramble onto his trousers,
pushing into the weave, trying to get a grip.
By the overhanging shirt I change
direction, traverse along his belt
to an earth-stained hand. The nails
are splintered and give good purchase,
the skin of his finger is smooth and thick
like warm ice. On his arm I discover
the glassy ridge of a scar, place my feet
gently in the old stitches and move on.
At his still firm shoulder, I rest for a while
in the shade, not looking down,
for climbing has its dangers, then pull
myself up the loose skin of his neck
to a smiling mouth to drink among teeth.
Refreshed, I cross the screed cheek,
to stare into his brown eyes, watch a pupil
slowly open and close. Then up over
the forehead, the wrinkles well-spaced
and easy, to his thick hair (soft and white
at this altitude), reaching for the summit,
where gasping for breath I can only lie
watching clouds and birds circle,
feeling his heat, knowing
the slow pulse of his good heart.
