+        Dominicus, Calarógæ in Hispánia ex nobili Gusmanórum família natus, Paléntiæ
+        liberálibus disciplinis et theologíæ operam dedit; quo in studio cum plurimum
+        profecísset, prius Oxoménsis ecclésiæ canonicus regularis, deínde ordinis fratrum
+        Prædicatórum auctor fuit. Hujus mater grávida sibi visa est, in quiete, continére in
+        alvo cátulum ore præferentem facem, qua, éditus in lucem, orbem terrárum incénderet.
+        Quo somnio significabátur fore ut, splendore sanctitátis ac doctrinæ, gentes ad
+        christianam pietátem inflammaréntur. Veritátem éxitus comprobávit; id enim et præstitit
+        per se, et per sui ordinis socios deinceps est consecutus.
+
+
+        Hujus autem ingenium ac virtus maxime enituit in everténdis hæreticis, qui
+        perniciosis erróribus Tolosátes pervertere conabántur; quo in negótio septem consumpsit
+        annos. Postea Romam venit ad Lateranense concílium cum episcopo Tolosano, ut ordo, quem
+        institúerat, ab Innocentio tertio confirmarétur. Quæ res dum in deliberatióne
+        versatur, Dominicus hortatu Pontificis ad suos revértitur, ut sibi regulam delígeret.
+        Romam rédiens, ab Honorio tertio, qui próximus Innocentio successerat, confirmatiónem
+        ordinis Prædicatórum ímpetrat. Romæ autem duo instituit monasteria, álterum virórum,
+        mulíerum álterum. Tres étiam mórtuos ad vitam revocávit, múltaque alia edidit miracula,
+        quibus ordo Prædicatórum mirifice propagari cœpit.
+
+
+        Verum, cum ejus ópera ubíque terrárum monasteria jam ædificaréntur, innumerabilésque
+        hómines religiosam ac piam vitam institúerent, Bononiæ anno Christi ducentésimo
+        vigesimo primo supra millesimum in febrem incidit. Ex qua cum se moriturum
+        intellígeret, convocátis frátribus et alumnis suæ disciplinæ, eos ad innocéntiam et
+        integritátem cohortátus est. Postremo caritátem, humilitátem, paupertátem, tamquam
+        certum patrimónium eis testaménto relíquit; fratribúsque orántibus, in illis verbis,
+        Subveníte, Sancti Dei, occúrrite, Angeli, obdormívit in Dómino, octavo Idus Augusti.
+        Quem póstea Gregórius nonus Pontifex rétulit in Sanctórum númerum.

+        Dominic was a Spaniard, a son of the noble family of Guzman. He was born at Calaruega,
+        in Old Castile, and was sent to be taught worldly and sacred learning at Palencia. He
+        attained great success in his studies, and became, first, a Regular Canon of the
+        Cathedral Church of Osma, and afterwards Founder of the Order of Friars Preachers. While
+        his mother was great with child, she dreamt that what was in her womb was a little whelp
+        dog with a lighted torch in his mouth, and that when she was delivered of him, he set all
+        the world on fire. By this dream was figured that burning and shining light of holiness
+        of life and power of doctrine, whereby he should enkindle godliness throughout whole
+        nations. The end proved the truth of the image, for this is in good sooth what his work
+        was, a work which he hath continued to do through the Brethren of his Order.
+
+
+        But his wisdom and bravery were most chiefly shown in confounding the heretics, who
+        were fain, with their pestilential falsehoods, to corrupt the people of the county of
+        Toulouse. In this business he spent seven years. Afterwards he came to Rome to the
+        Fourth Lateran Council, along with the Bishop of Toulouse, that the Order which he had
+        founded might be confirmed by Innocent III. While the matter was under consideration,
+        Dominick, by the advice of the Pope, went home, that he might put his Rule into shape.
+        He returned again to Rome, and obtained from Honorius III., the immediate successor of
+        Innocent, the confirmation of the Order of Preachers. At Rome Dominic founded two
+        Convents, one for men, and one for women. He raised three dead men to life, and worked
+        many other miracles, whereby the Order of Preachers became exceedingly spread abroad.
+
+
+        By his work convents were already during his life-time established in all countries,
+        and almost countless persons embraced the life of prayer and godliness. In the year of
+        Christ 1221 he fell sick of a fever at Bologna. When he understood that he was about to
+        die, he called together his brethren and disciples, and exhorted them to innocence and
+        uprightness. Lastly, he left to them as his legacy, love, lowliness, and poverty, and as
+        the brethren were all praying, and the words were being said, Come ye to help him, ye
+        Saints of God; run ye to meet him, ye Angels, he fell asleep in the Lord. Pope Gregory
+        IX. afterwards placed his name among those of the Saints.
