Henry Wadsworth Longfellow

Thou Royal River, born of sun and shower
  In chambers purple with the Alpine glow,
  Wrapped in the spotless ermine of the snow
  And rocked by tempests!--at the appointed hour
Forth, like a steel-clad horseman from a tower,
  With clang and clink of harness dost thou go
  To meet thy vassal torrents, that below
  Rush to receive thee and obey thy power.
And now thou movest in triumphal march,
  A king among the rivers!  On thy way
  A hundred towns await and welcome thee;
Bridges uplift for thee the stately arch,
  Vineyards encircle thee with garlands gay,
  And fleets attend thy progress to the sea!
