Wrake of the hapspurus

• Wreck of the Hesperus, a poem by Longfellow

• Wake of the Habsburgs, whose name is, on top of that, sometimes mispelled as 'Hapsburgs'

Soon after, there is another reference to the dynasty, [1] , as the one also found in the preceding chapter [2]

• spur

   * A rigid implement, often roughly y-shaped, that is fixed to one's heel 
   for purpose of prodding a horse. Often worn by, and emblematic of, 
   the cowboy or the knight.
   * Anything that inspires or motivates, as a spur does to a horse.  
   * An appendage or spike pointing rearward, near the foot, for instance 
   that of a rooster.
   * Any protruding part connected at one end, for instance a highway that 
   extends from another highway into a city.
   * Roots, tree roots, as in William Shakespeare's Cymbeline, Act IV, Scene II, 
    line 57:
                I do note 
                That grief and patience, rooted in them both, 
                Mingle their spurs together.
