IN PRÆSENTATIONE DOMINI: Ad Officium lectionis: Paulinus II aquileiensis?

I somehow missed this wonderful hymn for the Presentation. As I prepared to say the night office, I noticed the rubric which follows this hymn: Vel, ut ad II Vesperas, Quod chorus, i.e., the hymn at Vespers may be substituted for this following hymn:

Legis sacrátæ sanctis cæremóniis

subiéctus omnis cálamo Mosáico

dignátur esse, qui regit perfúlgidos

in arce Patris órdines angélicos,

cælúmque, terram fundávi ac mária.

Mater beáta carnis sub velámine

Deum ferébat úmeris castíssimis,

dúlcia strictis óscula sub lábiis

Deíque veri hominísque imprésserat

ori, iubénte quo sunt cuncta cóndita.

Hic lumen ardens géntium in óculis,

glória plebis Israélis gérminis;

pósitus hic est in ruínam scándali

et in salútem populórum ómnium,

donec secréta reveléntur córdium.

Glória Patri per imménsa sæcula,

sit tibi, Nate, decus et impérium,

honor, potéstas Sanctóque Spirítui:

sit Trinitáti salus indivídua

per infiníta sæculórum sæcula. Amen.

He who rules the brightly shining angelic orders in the heights of the Father, and who created heaven, earth and sea, is made wholly subject to rod of Moses with holy ceremonies of the holy law. The blessed Mother bears on her most chaste shoulders God under the veil of flesh, pressing sweet kisses on the lips of the mouth of the true God and man, by whose command all things were created. This is the burning light which shines upon the eyes of the Gentiles, the glory of the seed of his people Israel; this is he who is appointed for the fall of the stumbling block and for the salvation of all people, when the secrets of hearts are revealed. Glory to the Father through endless ages, to you, O Son, honor and authority, and honor and power to the Holy Spirit, praise to the undivided Trinity, through eternal ages. Amen.
