The context here is that the matronly year 1866 is on her way out, with Father Time pulling her offstage like a kite as he pirouettes a segue; the new year 1867 enters downstage as a comely danseuse, ready to pas de deux with Punchinello.  But what caught our eye is the middle-ground action — two clowns maintain a tension/equilibrium (a precursor to Bosonic — er, Bozo-nic — string theory?).  One is bald and stout, the other bearded and gaunt, but they joke around (literally in circles) as a concerted comedic constant.  These clowns may be our favorite Yin/Yang symbol to date!
