The thorns which I have reaped are of the tree
I planted—­they have torn me, and I bleed;
I should have known what fruit would spring from such a seed.
Childe Harold, Canto IV.  LORD BYRON.

                                 We but teach
  Bloody instructions, which, being taught, return
  To plague the inventor.  This even-handed justice
  Commends the ingredients of our poisoned chalice
  To our own lips.
Macbeth, Act i.  Sc. 7.  SHAKESPEARE. 
  So the struck eagle, stretched upon the plain,
  No more through rolling clouds to soar again,
  Viewed his own feather on the fatal dart,
  And winged the shaft that quivered in his heart.
English Bards and Scotch Reviewers.  LORD BYRON.

                        Remember Milo’s end,
  Wedged in that timber which he strove to rend.

REVENGE.

  Souls made of fire and children of the sun,
  With whom Revenge is virtue.
The Revenge, Act V.  DR. E. YOUNG

  And if we do but watch the hour,
  There never yet was human power
  Which could evade, if unforgiven,
  The patient search and vigil long
  Of him who treasures up a wrong.
Mazeppa.  LORD BYRON

  Vengeance is in my heart, death in my hand,
  Blood and revenge are hammering in my head.
Titus Andronicus, Act ii.  Sc. 3.  SHAKESPEARE

  If I can catch him once upon the hip,
  I will feed fat the ancient grudge I bear him.
Merchant of Venice, Act i.  Sc. 3.  SHAKESPEARE.

If it will feed nothing else, it will feed my revenge. Merchant of Venice, Act iii.  Sc.. 1.  SHAKESPEARE.

Vengeance to God alone belongs;
But when I think on all my wrongs,
My blood is liquid flame.
Marmion, Canto VI.  SIR W. SCOTT.

              Revenge, at first though sweet,
  Bitter ere long back on itself recoils.
Paradise Lost, Bk.  IX.  MILTON.

ROD, THE.

I pray ye, flog them upon all occasions. 
It mends their morals, never mind the pain.
Don Juan, Canto II.  LORD BYRON.

  Love is a boy by poets styled;
  Then spare the rod and spoil the child.
Hudibras, Pt.  II.  Canto I.  S. BUTLER.

  Whipping, that’s virtue’s governess,
  Tutoress of arts and sciences;
  That mends the gross mistakes of nature,
  And puts new life into dull matter;
  That lays foundation for renown,
  And all the honors of the gown.
Hudibras, Pt.  II.  Canto I.  S. BUTLER.

ROMANCE.

  Parent of golden dreams, Romance! 
    Auspicious queen of childish joys,
  Who lead’st along, in airy dance,
    Thy votive train of girls and boys.
To Romance.  LORD BYRON.
