MONOMACHIST — [Noun] One who fights in single combat; a duelist. From monomachy or monomakhia (from Greek μονομαχία, monomakhia, "single combat," from μόνος, monos, "alone" + μάχη, makhē, "battle") + the English suffix -ist (denoting an agent). Unlike a gladiator, a performer in orchestrated spectacle, or a soldier, a component of a tactical mass, the monomachist is a purist of singular confrontation. It is Hector stepping before Troy to face Achilles, the twenty measured paces at misty dawn, the bone-jarring transmission of force from one blade into another's parry—a ritual where the chaotic world contracts to the space between two beating hearts, a private argument meant to resolve a public world.
