As the Cœlian had a less prominent share in the history of Rome than any of the other hills, it preserves scarcely any historical monuments of pagan times. All those which existed under the republic were destroyed by a great fire which ravaged this hill in the reign of Tiberius,[155] except the Temple of the Nymphs, which once stood in the grove of the Camenæ, and which had been already burnt by Clodius, in order to destroy the records of his falsehoods and debts which it contained.[156] Some small remains in the garden of the Passionist convent are attributed to the temple which Agrippina raised to her husband the Emperor Claudius, and in S. Stefano Rotondo some antiquaries recognize the Macellum of Nero. There are no remains of the palace of the Emperor Tetricus, who lived here, "between the two sacred groves,"[157] in a magnificent captivity under Aurelian, whom he received here at a banquet, at which he exhibited an allegorical picture representing his reception of the empire of Gaul, and his subsequent resignation of it for the simple insignia of a Roman senator.[158] To the Christian visitor, however, the Cœlian will always prove of the deepest interest--and the slight thread of connection which runs between all its principal objects, as well as their nearness to one another, brings them pleasantly within the limits of a single day's excursion. Many of those who are not mere passing visitors at Rome, will probably find that their chief pleasure lies not amid the well-known sights of the great basilicas and palaces, but in quiet walks through the silent lanes and amid the decaying buildings of these more distant hills.
