Sparks of the torrid vapour that burned behind the bars

Of evening, broke dawn's rose, or smouldered in the stars,

Or lit the glowworm's taper, or wavered over the fen,

Or tipped the javelin of the far-ravening levin,

Lash of the Lord of Heaven and bitter scourge of sin.

O beautiful, O bright! my tired sinews strained

To this torch that flared and waned as a watery planet gloweth

And waneth in the night when a calm sea floweth

Under a misty sky spread with the tattered veils

Of rapid cloud driven over the deeps of heaven
