It is fascinating to follow Ruskin in his tours, and understand his meticulous concern for finding the truth of each artist through his art. Like Winckelmann before him, he considered it essential to distinguish the original from restoration. In Florence, he chooses Giotto as the main theme for visits to illustrate his artistic development. As a background, he first gives a brief but thorough historical survey to the topographical, social and religious situation. The visitor is then conducted (with ‘your Murrays’s Guide’) to Santa Croce to see St. Louis of Toulouse high up in a chapel, a key figure for the understanding of Giotto, painted in his most mature period. On the way, an explanation is also given on why Arnolfo da Gambio has not vaulted the church but built a simple wooden ceiling, and why there is no apse.
