At a distance of fifteen miles from Velletri, we passed a convent, which is built opposite the spot where St. Paul was met by his friends, on his journey from the seaside to Rome. The canal upon which Horace embarked on his celebrated journey to Brundusium, runs parallel with the road for its whole distance. This marshy desert is inhabited by a race of as wretched beings, perhaps, as are to be found upon the face of the earth. The pestiferous miasma of the pools is certain destruction to health, and the few who are needed at the distant post-houses, crawl out to the road-side like so many victims from a pest-house, stooping with weakness, hollow-eyed, and apparently insensible to everything. The feathered race seems exempt from its influence, and the quantities of game of every known description are incredible. The ground was alive with wild geese, turkeys, pigeons, plover, ducks, and numerous birds we did not know, as far as the eye could distinguish. The travelling books caution against sleeping in the carriage while passing these marshes, but we found it next to impossible to resist the heavy drowsiness of the air. At Terracina the marshes end, and the long avenue of elms terminates at the foot of a romantic precipice, which is washed by the Mediterranean. The town is most picturesquely built between the rocky wall and the sea. We dined with the hollow murmur of the surf in our ears, and then, presenting our passports, entered the kingdom of Naples. This Terracina, by the way, was the ancient _Anxur_, which Horace describes in his line-- "Impositum late saxis candentibus Anxur." For twenty or thirty miles before arriving at Terracina, we had seen before us the headland of Circoeum, lying like a mountain island off the shore. It is usually called San Felice, from the small town seated upon it. This was the ancient abode of the "daughter of the sun," and here were imprisoned, according to Homer, the champions of Ulysses, after their metamorphoses. From Terracina to Fondi, we followed the old Appian way, a road hedged with flowering myrtles and orange trees laden with fruit. Fondi itself is dirtier than imagination could picture it, and the scowling men in the streets look like myrmidons of Fra Diavolo, their celebrated countryman. This town, however, was the scene of the romantic story of the beautiful Julia Gonzaga, and was destroyed by the corsair Barbarossa, who had intended to present the rarest beauty of Italy to the Sultan. It was to the rocky mountains above the town that she escaped in her night-dress, and lay concealed till the pirate's departure. In leaving Fondi, we passed the ruined walls of a garden said to have belonged to Cicero, whose tomb is only three leagues distant. Night came on before we reached the tomb, and we were compelled to promise ourselves a pilgrimage to it on our return.
