“Igneus est ollis vigor, et cœlestis origo Seminibus.”

Could I hit on a theme
  To fashion my verse on,
Not long would I seem
  A lack-courtesy person.
But I have not the skill,
  Nor talisman strong,
To summon at will
  The Spirit of song.—
Bright thoughts are roaming
  Unseen in the air;
Like comets, their coming
  Is sudden and rare.
They strike, and they enter,
  And light up the brain,
Which thrills to its centre
  With rapturous pain. Where the chance-seed
  Is piously nursed,
Brighter succeed
  In the path of the first.—
One sighs to the Muse,
  Or the sweet nightingale,
One sips the night-dews
  Which moon-beams exhale.
All this is a fiction;
  I never could find
A suitable friction
  To frenzy my mind.
What use are empirics?
  No gas on their shelf
Can make one spout lyrics
  In spite of oneself!

Dartington. July 18, 1831.
