Rome was not Built in a Day.
Achievements of great pith and moment are not accomplished without patient perseverance and a considerable interval of time. The French say, Grand bien ne vient pas en peu dheures, but the English proverb is to be found in the French also: Rome na pas été faite en un jour. (1615.)

Rome was not built in a day, like Anchiale, of Cilicia, where Sardanapalus was buried. It is said that Anchiale was actually built in a day.
