Stone at Newgrange photo by Johnbod. https://en.wikipedia.org/wiki/User:Johnbod.
A man is carving shapes:
spirals, lozenges, chevrons;
the sun is looking over his shoulder.
Below, in the valley, the Boyne passes
with a glint from its teeth,
the whitethorn is in full bloom,
the daylight hours are long.
His hands are leather from handling flint;
a wave traverses the stone,
arcs toss on the crests,
they tip left then right;
tonight the moon is tipping left;
in three weeks daytime will be at its longest.
