Premise: The General Council Hall (Sala del Consiglio Generale) is dominated by the works of his vigorous St. George (1416), intended for the Orsanmichele ; his important David, naked and restless in bronze (1450); and the stone Marzocco lion, the town's symbol, from the Palazzo Vecchio.

Hypothesis: There are no masterpieces worth viewing in the General Council Hall.
