morning, noon
The young travellers were just beginning to experience the charm which belongs peculiarly to journeying in Italy -- that of finding , one after another , these delightful old cities , each in its own characteristic setting of country , of history , of legend and romance . They were full of the thrill of expected emotion , -- that most delicious of all sensations . And they received no disappointment from this old `` red city . '' They saw its beautiful , incomparably beautiful , Cathedral , full of richness of sculpture and color in morning , noon , and evening light ; and were never tired of admiring every part of it , from its graffito and mosaic pavement to its vaulted top filled with arches and columns , that reminded them of walking through a forest aisle and looking up through the interlaced branches of trees . They visited the Cathedral Library , whose walls are covered with those historical paintings by Pinturrichio , the little deaf Umbrian painter , in whose design Raphael is said to have given aid . But Mr. Sumner wished that the time they could give to the study of paintings be spent particularly among the works of the old Sienese masters . So they went again and again to the Accademia delle Belle Arti and studied those quaint , half-Byzantine works , full of pathetic grace , by Guido da Siena , by Duccio , Simone Martini , Lippo Memmi , and the Lorenzetti brothers .
