INVISIBLE CITIES XXIX -- Thin Cities: SOPHRONIA

1. "Sophronia" means "self-controlled" or "sensible."  If the half-city that bears permanently the name, Sophronia, is the carnival, then what is Polo (I daren't say Calvino here) getting at?
2. The two preceding cities, both Olivia and, if you're willing to stretch a little, the unnamed city of departures, both hold as part of themselves a reflection, double, or twin--a repetition of itself (herself?).  Is this the motif?
3. What do you think of Calvino's imagination?
4. Is the banking, concrete half a reflection of or just a balance of mass to the permanent half?
