On Snow

From Heaven I fall, though from earth I begin,
No lady alive can show such a skin.
I'm bright as an angel, and light as a feather,
But heavy and dark, when you squeeze me together.
Though candour and truth in my aspect I bear,
Yet many poor creatures I help to ensnare.
Though so much of Heaven appears in my make,
The foulest impressions I easily take.
My parent and I produce one another,
The mother the daughter, the daughter the mother.
