Don Orsino Saracinesca is of the younger age and lives in the younger Rome, with his father and mother, under the roof of the vast old palace which has sheltered so many hundreds of Saracinesca in peace and war, but which has rarely in the course of the centuries been the home of three generations at once during one and twenty years. The lover of romance may lie in the sun, caring not for the time of day and content to watch the butterflies that cross his blue sky on the way from one flower to another. But the historian is an entomologist who must be stirring. He must catch the moths, which are his facts, in the net which is his memory, and he must fasten them upon his paper with sharp pins, which are dates.
