“In lieu of descending to follow the Via Aurelia where it wound down a few miles off the coast, by Santa Maranella and Santa Severa and mediæval Palo, and the volcanic soil and the steep ravines by Cervetri, where the long avenues of cliff-sepulchres are all that remain to show the site of Cære, and gaining so the mouth of Tiber to ascend the stream in any boat that he might find by Fiumicino, he still struck across the country by cattle-tracks known alone to himself and wild men like him, and chose to leave the Maccarese morasses untrodden in his rear, and had followed the course of the Arrone River as far as the high cliffs up by forsaken Galera.”
