Twentieth-century Harmonics editions print a completed mathematical music text under Ptolemy’s name. A specialist acoustic-mathematical book is an elite-access object; the improving row is the public edition itself. In the causal graph this event weakens Social Cohesion, a driver that strengthens Having a say in government — a worsening welfare path.
