A little beyond this, attached to the Church of S. Vito, from which it has sometimes been named, is the Arch of Gallienus (supposed to occupy the site of the Esquiline gate in the wall of Servius), dedicated to Gallienus (A.D. 253—260) and his Empress Salonina, by Marcus Aurelius Victor, evidently a court-flatterer of the period, who was prefect of Rome, and possessed gardens on this spot. It is of very inferior execution; the original plan had three arches; only that in the centre remains, but traces of another may be seen on the side next the church. Gallienus was a cruel and self-indulgent emperor, who excited the indignation of the Romans by leaving his old father, Valerian, to die a captive in the hands of the Persians, so that the inscription, "Clementissimo principi cuius invicta virtus sola pietate superata est," is singularly false, even for the time.

"Il arrivait à Gallien de faire tuer trois ou quatre mille soldats en un jour, et il écrivait des lettres comme celle-ci, adressée à un de ses généraux: 'Tu n'auras pas fait assez pour moi, si tu ne mets à mort que des hommes armés, car le sort de la guerre aurait pu les faire périr. Il faut tuer quiconque a eu une intention mauvaise, quiconque a mal parlé de moi. Déchire, tue, extermine: lacera, occide, concide.' Entré dans Byzance en promettant leur pardon aux troupes qui avaient combattu contre lui, il les fit égorger, et les soldats ravagèrent la ville au point qu'il n'y resta pas un habitant. Voilà pour la clémence. Tandis que Valérien, son père, était prisonnier du roi des Perses Sapor, qui pour monter à cheval se servait du dos du vieil empereur comme d'un marchepied, en attendant qu'il le fit empailler, l'indigne fils de Valérien vivait au sein des plus honteuses voluptés, et ne tentait pas un seul effort pour le délivrer. Voilà pour la vaillance et la piété."—Ampère, Emp. ii. 334.

Close to this Gallienus had ordered a statue of himself to be erected, which was to be double the height of the colossus of Nero, but it was unfinished at the time of his death, and destroyed by his successor. From the centre of the arch hung, from the thirteenth century, the chain and keys of the gates of Viterbo, removed at the same time as the great bell of the Capitol. These interesting memorials of middle-age warfare were taken down in 1825.

Passing under the arch we enter upon the Via Maggiore, the main artery leading to Santa Croce. On the left is the humble convent of the Monache Polacche, where the long-suffering Madre Makrena, the sole survivor of the terrible persecution of the nuns of Minsk, has lived in the closest retirement since her escape in 1845.

The story of the cruel sufferings of the Polish-Basilian nuns of Minsk reminds one of the worst persecutions of the early Christians, under Nero and Diocletian. Makrena Miaczylslawska was abbess of a convent of thirty-eight nuns, whom the apostate bishop Siemasko first tried to compel to the Greek faith in the summer of 1838. Their refusal led to their being driven, laden with chains, to Witepsk, in Siberia, where they were forced to hard labour, many of them being beaten to death, one roasted alive in a hot stove, and another having her brains beaten out with a stake by the abbess of the Czernice (apostate nuns), on their persisting in their refusal to change their religion. In 1840 the surviving nuns were removed to Polock, where they were forced to work at building a palace for the bishop Siemasko, and where nine of them perished by a falling scaffold, and many others expired under the heavy weights they were compelled to carry, or under the lash. In 1842 their tortures were increased tenfold, eight of the sisters having their eyes torn out, and others being trodden to death. In 1843 those who still survived were removed to Miadzioly, where the "protopope Skrykin" said that he would "drown them like puppies," and where they were dragged by boats through the shallows of the half-frozen Dwina, up to their necks in water, till many died of the cold. In the spring of 1845, Makrena, with the only three nuns who survived with the use of their limbs (Eusebia Wawrzecka, Clotilda Konarska, and Irene Pomarnacka,) scaled the walls of their prison, while the priests and nuns who guarded them were lying drunk after an orgie, and, after wandering for three months in the forests of Lithuania, made good their escape. The nuns remained in Vienna; the abbess, after a series of extraordinary adventures, arrived in Rome, where she was at first lodged in the convent of the Trinità de' Monti. The story of the nuns of Minsk was taken down from her dictation at the same time by a number of eminent ecclesiastics, authorized by the pope, and the authenticity of her statements verified; after which she retired into complete seclusion in the Polish convent on the Esquiline, where she has long filled the humble office of portress. Her legs are eaten into the bone by the chains she wore in her prison life. The story of the persecution at Minsk may be read in "Le Récit de Makrena Miaczylslawska," published at Paris, by Lecoffre, in 1846; in a paper by Charles Dickens, in the "Household Words," for May, 1854; and in "Pictures of Christian Heroism," 1855.

Nearly opposite this convent is the picturesque ruin of a nymphæum, probably of the time of Septimius Severus, erroneously called The Trophies of Marius, from the trophies, now on the terrace in front of the Capitol, which were found here.

Beyond this, on the right, is the entrance of the Villa Palombara, occupying a great part of the site of the Baths of Titus.

"This villa once belonged to Queen Christina of Sweden, who has left upon the little doorway exactly opposite the ruin called the Trophies of Marius, a curious record of her credulity. It consists of a collection of unintelligible words, signs, and triangles, given her by some alchymist, as the rule to make gold, and which, no doubt, he had found successful, having obtained from her, and probably from many other votaries, abundance of that precious metal in exchange for it. But as she could make nothing of it, she caused it to be inscribed here, in case any passenger, wiser than herself, should be able to develope the mystic signs of this golden secret."—Eaton's Rome.

Though the existing ruin is misnamed, the trophies erected in honour of the victories which Marius gained over the Cimbri were really set up near this; and, curiously enough, on this site also Marius was defeated at the "Forum Esquilinum" by Sylla, who suddenly descended upon Rome from Nola with six legions, and entering by the Porta Esquilina, met his adversary here, and forced him to fly to Ostia.

Behind the Trophies of Marius a lane branches off on the left to the desolate Church of Sta. Bibiana.
