And we who see them but a lens
Refracting heavenly light?—

And crystalline as rays of light
Direct from heaven, their source divine;
Refracted through the mist of years,
How red my setting sun appears,
How lurid looks this soul of mine!

But it is choked with nettles and obscene
And phallic fungi rot there as they grow.
