[It needs some familiarity with the Florentine chroniclers to understand that the words quoted by no means indicate that the families named were not of patrician origin.

"There walked into the lobby with the Radicals, Lord -- -- and Mr .-- --," would just as much prove that the persons named had not belonged to the class of landowners.

But the passage is interesting as showing the great care she took to make her Italian novel historically accurate.
