• Capraia and Gorgona are two islands opposite the mouth of the Arno. Ampère, Voyage Dantesque , 217, remarks:⁠— “This imagination may appear grotesque and forced if one looks at the map, for the isle of Gorgona is at some distance from the mouth of the Arno, and I had always thought so, until the day when, having ascended the tower of Pisa, I was struck with the aspect which the Gorgona presented from that point. It seemed to shut up the Arno. I then understood how Dante might naturally have had this idea, which had seemed strange to me, and his imagination was justified in my eyes. He had not seen the Gorgona from the Leaning Tower, which did not exist in his time, but from some one of the numerous towers which protected the ramparts of Pisa. This fact alone would be sufficient to show what an excellent interpretation of a poet travelling is.” ↩
