[57] The gemelli are, in all probability, the large twin reservoirs just outside the western wall of the Sessorium, now in a large vineyard near the Porta Maggiore, through which the Neronian arches pass. These reservoirs are below the level of the specus of the Anio Vetus, as was shewn by some excavations made in them under my direction in 1869.
[58] Some of the water had been thrown into the old specus at the junction of the Claudian with the Neronian arches.
[59] There are remains of more than one specus crossing the valley from the Cœlian to the Aventine upon the agger of Servius Tullius, and passing over the Porta Capena at the foot of the Cœlian. One of these was the Marcia, from the reservoir over the Arch of Dolabella, which is near the site of the Claudium and Temple of Claudius. There were great reservoirs for the aqueducts at this point on different levels; one of them underground is still in use, the remains of the others are among the most picturesque objects in Rome. This passage cannot apply to the temple of Hope, which is full a mile away from the Aventine.
[60] “Quum hæc accepta clades esset, jam C. Horatius et T. Menenius consules erant. Menenius adversus Tuscos, victoria elatos, confestim missus. Tum quoque male pugnatum est, et Janiculum hostes occupavere: obsessaque urbs foret, super bellum annona premente, (transierant enim Etrusci Tiberim) ni Horatius consul e Volscis esset revocatus: adeoque id bellum ipsis institit mœnibus, ut primo pugnatum ad Spei sit æquo Marte, iterum ad Portam Collinam. Ibi quanquam parvo momento superior Romana res fuit, meliorem tamen militem, recepto pristino animo, in futura prœlia id certamen fecit.” (Livii Hist., lib. ii. c. 51.)
[61] “Romæ fœdum incendium per duas noctes ac diem unum tenuit: solo æquata omnia inter Salinas ac Portam Carmentalem cum Æquimælio Jugarioque vico. In templo Fortunæ ac matris Matutæ et Spei extra portam late vagans ignis, sacra profanaque multa absumpsit.” (Ibid., lib. xxiv. c. 47.)
[62] “Comitia deinde a prætore urbano de senatus sententia plebisque scito sunt habita: quibus creati sunt quinqueviri muris turribusque reficiendis: et triumviri bini; uni sacris conquirendis donisque persignandis; alteri reficiendis ædibus Fortunæ et matris Matutæ intra Portam Carmentalem, sed et Spei extra portam, quæ priore anno incendio consumptæ fuerant.” (Livii Hist., lib. xxv. c. 7.)
[63] “Theatrum et proscenium ad Apollinis, ædem Jovis in Capitolio, columnasque circa poliendas albo locavit: et ab his columnis, quæ incommode opposita videbantur, signa amovit: clipeaque de columnis, et signa militaria affixa omnis generis dempsit. M. Fulvius plura et majoris locavit usus: portum et pilas pontis in Tiberim; quibus pilis fornices post aliquot annos P. Scipio Africanus et L. Mummius censores locaverunt imponendos; basilicam post argentarias novas et forum piscatorium, circumdatis tabernis, quas vendidit in privatum; et forum, et porticum extra Portam Trigeminam, et aliam post navalia, et ad fanum Herculis, et post Spei ad Tiberim ædem Apollinis Medici.” (Ibid., lib. xl. c. 51.)
[64] “Sive autem medii montes erunt inter mœnia et caput fontis, sic erit faciendum, uti specus fodiantur sub terra librenturque ad fastigium,” &c. (Vitruv., De Architectura, lib. viii. c. 6. § 3.)
[65] “Alexandria est fere tota suffossa, specusque habet ad Nilum pertinentes, quibus aqua in privatas domos inducitur.” (Aulus Hirtius, De Bello Cæsaris Alexandrino, cap. 4.)
[66] Frontinus, lib. i. c. 7. He also quotes from Fenestella concerning the delays which occurred, and speaks of the Decemvirs consulting the Sybilline books, and being supposed to have found that it was not the Marcian but rather the Anio which should be brought into the Capitol: (“Invenisse dicuntur, non esse aquam Marciam, sed potius Anionem in Capitolium perducendam.”) Eventually, however, Marcius prevailed, and his plan was carried out.
