Import St. Gregory the Great's own proper Lauds/Vespers content

Live-verified against Divinum Officium (Monastic Tridentinum 1617),
2033-03-12 (clean year, per his own saint file's comment). Own chapter
(Eccli 50:1, "Ecce sacérdos magnus... suffúlsit domum") and own hymns at
both hours ("Mella cor obdulcántia" Lauds, "Anglórum jam Apóstolus"
Vespers, the latter recounting his sending Augustine of Canterbury and
the "non Angli sed Angeli" legend); responsory and versicle turn out
byte-identical to Common-of-a-Confessor-Bishop's own, reused verbatim.
Neither hymn has an English rendering in the reference engine at all --
own original translations, marked draft.

+    Anglórum jam Apóstolus,
+
+    Nunc Angelórum sócius,
+
+    Ut tunc, Gregóri, Géntibus,
+
+    Succúrre jam credéntibus.
+
+
+    Tu largas opum cópias,
+
+    Omnémque mundi glóriam
+
+    Spernis, ut inops ínopem
+
+    Jesum sequáris príncipem.
+
+
+    Vidétur egens náufragus,
+
+    Dum stipem petit Ángelus:
+
+    Tu munus jam post géminum
+
+    Præbes et vas argénteum.
+
+
+    Ex hoc te Christus témpore
+
+    Suæ præfert Ecclésiæ:
+
+    Sic Petri gradum pércipis,
+
+    Cujus et normam séqueris.
+
+
+    O Póntifex egrégie,
+
+    Lux et decus Ecclésiæ,
+
+    Non sinas in perículis,
+
+    Quos tot mandátis ínstruis.
+
+
+    Sit Patri laus ingénito,
+
+    Sit decus Unigénito,
+
+    Sit utriúsque párili
+
+    Majéstas summa Flámini. Amen.

+    Once the English nation's apostle,
+
+    Now companion of the blest;
+
+    As then to nations, Gregory,
+
+    Now come to aid the faith confessed.
+
+
+    Abundant riches you disdained,
+
+    And all the glory of the world,
+
+    That, poor yourself, you might pursue
+
+    The poor Prince Jesus, banner unfurled.
+
+
+    A shipwrecked beggar seemed to stand,
+
+    An angel asking alms of thee:
+
+    Twice having given, yet again
+
+    You gave a vessel, silver, free.
+
+
+    From that hour Christ sets you over
+
+    His own Church, to steer and guide:
+
+    So Peter's rank is yours to hold,
+
+    Whose rule you follow at his side.
+
+
+    O Bishop excellent and true,
+
+    Light and adornment of the Church,
+
+    Forsake not, in their perils, those
+
+    Whom you instructed in your search.
+
+
+    To the unbegotten Father praise,
+
+    To the Only-begotten glory be:
+
+    To both alike, in equal state,
+
+    The Spirit's highest majesty. Amen.
