DESCRIPTION:In 1867 Lord Kelvin suggested that elementary particles can be
  knotted fluid vortices in the aether. While his idea was revolutionary fo
 r his time\, our present experimental knowledge does not agree with his co
 njecture. Nevertheless\, the idea is attractive for its simplicity of rela
 ting fundamental physical and mathematical objects. In that spirit we mode
 l the observed J^{++} mesonic mass spectrum in terms of energies for tight
 ly knotted and linked chromoelectric QCD flux tubes. The data is fitted wi
 th one and two parameter models. We predict one new state at 1200 MeV and 
 a plethora of new states above 1700 MeV.\n
