The Tree Is Here, Still, In Pure Stone

The tree is here, still, in pure stone,
in deep evidence, in solid beauty,
layered, through a hundred million years.
Agate, cornelian, gemstone
transmuted the timber and sap
until damp corruptions
fissured the giant's trunk
fusing a parallel being:
the living leaves
unmade themselves
and when the pillar was overthrown
fire in the forest, blaze of the dust-cloud,
celestial ashes mantled it round,
until time, and the lava, created
this gift, of translucent stone.
