Augustus J. C. Hare,
Walks in Rome
“ Of all these various buildings nothing remains except the Pantheon, a single arch of the Baths of Agrippa, some disfigured fragments of the Mausoleum, a range of columns belonging to the temple of Neptune, and a portion of the Portico of Octavia. The interest of the Campus Martius is almost entirely mediæval or modern, and the objects worth visiting are scattered amid such a maze of dirty and intricate streets, that they are seldom sought out except by those who make a long stay in Rome, and care for everything connected with its history and architecture. ”
