Written On A Lady’s Fan

In ancient times when like La Mancha's Knight
  The adventurous Hero sallied forth to fight,
  Some sage Magician famous in Romance
  Supplied the Warrior with a wonderous lance,
  With which through adverse troops he forced his way,
  And won from giant hosts the doubtful day.
  But I more fatal arms to you impart,
  By Venus forged to wound the human heart:
  This Weapon placed in your victorious hand
  No cunning shall elude, no force withstand,
  Nor shall the brave resist, or coward fly,
  But all Mankind submit, adore, or die.
