Opposite this, is the Cistercian convent and Church of S. Bernardo, a rotunda of the Baths of Diocletian, turned into a church in 1598, by Caterina Sforza, Contessa di Santa Fiora.

Hence the Via della Porta Pia leads to the Quattro Fontane. On the left is the small Church of S. Caio, which encloses the tomb of that pope, inscribed "Sancti Caii, Papæ, martyris ossa." Further, on the left, is the great recently suppressed convent of the Carmelites, and the Church of Sta. Teresa. The right of the street is bordered by the orange-shaded wall of the Barberini garden.

Between S. Caio and Sta. Teresa, is the Studio of Overbeck, the venerable German devotional painter, who died 1869. His daughter allows visitors to be admitted on Sunday afternoons.

CHAPTER XII.
THE ESQUILINE.

Golden House of Nero—Baths of Titus and Trajan—S. Pietro in Vincoli—Frangipani Tower—House of Lucrezia Borgia—S. Martino al Monte—Sta. Lucia in Selce—Sta. Prassede—Santissimo Redentore—Arch of Gallienus—Trophies of Marius—Sta. Bibiana—Temple of Minerva Medica—S. Eusebio—S. Antonio Abbate—Sta. Maria Maggiore.

THE Esquiline, which is the largest of the so-called 'hills of Rome,' is not a distinct hill, but simply a projection of the Campagna. "The Quirinal, Viminal, Esquiline, and Cœlian stretch out towards the Tiber, like four fingers of a hand, of which the plain whence they detach themselves represents the vast palm. This hand has seized the world."[250]

Varro says that the name Esquiline was derived from the word excultus, because of the ornamental groves which were planted on this hill by Servius Tullius,—such as the Lucus Querquetulanus, Fagutalis, and Esquilinus.[251] The sacred wood of the Argiletum long remained on the lower slope of the hill, where the Via Sta. Maria dei Monti now is.

The Esquiline, which is still unhealthy, must have been so in ancient times, for among its temples were those dedicated to Fever, near Sta. Maria Maggiore—to Juno Mephitis,[252] near a pool which emitted poisonous exhalations—and to Venus Libitina,[253] for the registration of deaths, and arrangement of funerals. As the hill was in the hands of the Sabines, its early divinities were Sabine. Besides those already mentioned, it had an altar of the Sabine sun-god Janus, dedicated together with an altar to Juno by the survivor of the Horatii,[254] and a temple of Juno Lucina, the goddess of birth and light.

"Monte sub Esquilio multis incæduus annis
Junonis magnæ nomine lucus erat."
Ovid, Fast. ii. 435.

This hill has two heights. That which is crowned by Santa Maria Maggiore was formerly called Cispius, where Servius Tullius had a palace; that which is occupied by S. Pietro in Vincoli was formerly called Oppius, where Tarquinius Superbus lived. It was in returning to his palace on the former (and not on the latter height, as generally maintained) that Servius Tullius was murdered.
