Ibsen's four years in Italy were years of rest, of solitude, of calm. The attitude of Ibsen to Italy was totally distinct from that of other illustrious exiles of his day and generation. The line of pilgrims from Stendhal and Lamartine down to Ruskin and the Brownings had brought with them a personal interest in Italian affairs; Italian servitude had roused some of them to anger or irony; they had spent nights of insomnia dreaming of Italian liberty. Casa Guidi Windows may be taken as the extreme type of the way in which Italy did not impress Ibsen.
