To A Snowflake

What heart could have thought you? --
Past our devisal
(O filigree petal!)
Fashioned so purely,
Fragilely, surely,
From what Paradisal
Imagineless metal,
Too costly for cost?
Who hammered you, wrought you,
From argentine vapor? --
"God was my shaper.
Passing surmisal,
He hammered, He wrought me,
From curled silver vapor,
To lust of His mind --
Thou could'st not have thought me!
So purely, so palely,
Tinily, surely,
Mightily, frailly,
Insculped and embossed,
With His hammer of wind,
And His graver of frost."
