Pyrrhichios

The Pyrrhichios or Pyrrhike dance ("Pyrrhic dance"; Ancient Greek: πυρρίχιος or πυρρίχη,^[1] but often misspelled as πυρρίχειος or πυρήχειος) was the best known war dance of the Greeks. It was probably of Dorian origin and practiced at first solely as a training for war. According to ancient sources, it was a weapon dance.^[2]
