+        Marcellus Romanus, a Constantio et Galerio usque ad Maxéntium pontificátum gessit. Cujus
+        hortatu Lucina matrona Romana, bonórum suórum Dei Ecclésiam fecit heredem. Aucto in Urbe
+        fidelium numero, ad eórum utilitátem, ad baptismum pœnitentiámque dandam eis, qui christianam
+        religiónem suscíperent, et ad Mártyrum sepultúram, novos Titulos instituit, et quasi álteras
+        diœcéses distríbuit. Quibus rebus ira incénsus Maxentius, Marcello gravia supplícia minátur,
+        nisi, depósito pontificatu, idolis immoláret.
+
+
+        Qui cum insanas hóminis voces neglígeret, misit eum in catábulum, ut bestiárum, quæ publice
+        alebántur, curam sustinéret: ubi Marcéllus assiduis jejuniis et precibus novem menses vitam
+        duxit, parochias, quas præsens non póterat, visitans per epistolas. Inde ereptus a clericis,
+        hospítio recípitur a beáta Lucina, in cujus ædibus ecclésiam dedicávit, quæ hódie titulo
+        sancti Marcelli nominátur: in qua et Christiáni orábant, et ipse beátus Marcellus
+        prædicabat.
+
+
+        Quibus cógnitis, Maxéntius in eam ecclésiam catábuli bestias transférri, et a Marcello
+        custodiri jubet: ubi loci fœditate, multisque ærumnis afflíctus obdormívit in Dómino. Cujus
+        corpus in cœmeterio Priscillæ via Salaria a beáta Lucina sepúltum est décimo septimo Kalendas
+        Februarii. Sedit annos quinque, mensem unum, dies viginti quinque. Scripsit epistolam ad
+        episcopos Antiochenæ provinciæ de primatu Romanæ Ecclésiæ, quam caput ecclesiárum
+        appellandam demonstrat; ubi étiam illud scriptum est, nullum concílium jure celebrari, nisi
+        ex auctoritáte Romani Pontificis. Ordinávit mense Decembri Romæ presbyteros viginti quinque,
+        diaconos duos, episcopos per diversa loca viginti unum.

+        This Marcellus was a Roman, and held the supreme Pontificate from (the year of our Lord 304,
+        in) the reign of Constantius and Galerius, till (310, in) that of Maxentius. It was through
+        his persuasion that the Roman lady Lucina left the whole of her property to the Church of
+        God. As the believers increased, he instituted new titles in the City, which he divided
+        after the manner of dioceses for their convenience, and for the baptism and penance of
+        heathens converted to Christianity, and for the burial of the martyrs. These proceedings
+        excited the wrath of Maxentius, who threatened Marcellus with the heaviest punishment,
+        unless he would lay down the Popedom and sacrifice to idols.
+
+
+        The servant of God treated with contempt the mad cries of this man, who accordingly took him
+        and sent him to a menagerie, to take care of the beasts which were fed at the public cost.
+        Marcellus remained at this place for nine months, which he spent in continual fasting and
+        prayer, and, as he could not visit the parishes in person, he wrote letters to them. Some
+        clerks rescued him, and the blessed Lucina hospitably received him into her house, in which
+        he dedicated a Church, which is now called St. Marcellus'. Here the Christians met to pray,
+        and the blessed Marcellus himself preached.
+
+
+        These proceedings came to the knowledge of Maxentius, who thereupon had the wild beasts
+        brought from the menagerie and located in the church, where Marcellus was made to feed them.
+        The noisomeness of the place and the filthiness of his occupation broke down a constitution
+        already enfeebled by many ailments, and he fell asleep in the Lord. The blessed Lucina
+        buried his body in the cemetery of Priscilla, on the Salarian Way, on the 16th of January.
+        He sat on the throne of Peter for five years, one month, and twenty-five days. He wrote an
+        epistle to the Bishops of the Patriarchate of Antioch on the primacy of the Roman Church,
+        wherein he proveth the right of the same Church to be called the head of all the Churches.
+        In this letter he likewise saith that no Council can be lawfully gathered together except by
+        the authority of the Roman Pontiff. He ordained at Rome in the month of December
+        twenty-five Priests, two Deacons, and twenty-one Bishops for diverse Sees.
