Here is a hymn of teh Mozarabic rite from teh second Sunday of Easter;
Te centies mille legionum Angeli
Concentu plaudunt, et canora jubilant,
Christe Jesu Alpha et Omega omnipotens,
Sepultus olim, et vivens in saecula,
Testis fidelis, et verum principium.
Qui mundi hujus dejecisti principem,
Redimens Orbem tuo almo Sanguine;
Sanctus et verus Genitus Ingeniti,
Reserans clausum, et apertum obstruens,
Faciens nos Deo Regni Sacerdotium.
Tu verus Agnus solus sine macula,
Qui dextram Patris conlocatus solio,
Solus egressus ab arce Dominica,
Similis Jaspidi, et Sardino lapidi,
Iris per gyrum, smaragdus circuis.
Tu Dei pignus, hominisque Filius,
Septies librum signatum signaculis
Solvere signa dignus repertus es:
Agnus occisus septem pollens cornibus,
Septeno fulgens et lumine flammeo.
E throno prodeunt fulgura, et tonitrua,
Septem ardentes ante thronum lampades,
Septem ubique missi Dei Spiritus,
Septem stellae micant Agni dextera,
Septem cui adstant candelabra aurea.
Sedentes circuм quater seni Primates,
Amicti cuncti niveis cycladibus,
Et laureati diademis aureis,
Aureas vehunt phialas aromatum,
Aureis psallunt modulis, et citharis.
Stant ante Thronum nitet mare vitreum,
Bis bini fortes, idem animalia:
Homo per genus, leo voce perstrepit
Juvencus ore promit Sacerdotium,
Petens ad astra more volans aquilae.
Quatuor formis senis alis singulis,
Ante et retro cuncta plena oculis,
Vigiles semper dormiendi nescii,
Vicissim Sanctus ter clamantes jugiter,
Illi, qui erat, est, et qui venturus est.
Gloria Patri, laus, sapientia
Agno sedenti supra Thronum in coelis;
cuм Patre regnat, et cuм Sancto Spiritu,
Connexa simul tribus una Deitas,
Per infinita saeculorum saecula.
Amen.
Which roughly translated means;
You hundreds of thousands of angels
In harmony, hug, in a melodious cry out,
Jesus Christ, the Alpha and the Omega, the Almighty,
He was buried in the past, and he shall live for ever,
The faithful witness, and the truth of the principle.
He cast the prince of this world,
Buys sphere of your Holy Blood;
Holy and true upto talent
Unlocking the closed and open obstruens,
Making God a kingdom of priests.
You alone are the true Lamb without blemish,
Who's right hand placed on a seat,
Out alone from the fortress Sunday,
It is like a jasper and a sardine stone,
By means of the circle of the iris, and a carbuncle circuit.
You are a pledge of God, Son of man,
Seven times book sealed seals
Loosen standards worthy art:
Lamb slain seven powerful horns,
Seven bright light and flaming.
Out of the throne come forth lightnings, and thunders,
Seven lamps burning before the throne,
Seven of the masses,
Seven stars twinkle Lamb right,
Whom stands seven candlesticks.
Sitting around a four sixes Primates
Dressed all in snowy Cyclades,
And the golden laurel crown,
Mounts golden bowls of spices,
Of gold, chant the rhythm, and with harps.
Standing in front of the throne a sea of glass is shining,
Twice two kinds of mighty men, the same as the animals:
It is through these kind of, resounds the voice of a lion,
Prom juvencus mouth priesthood
In seeking to stars more flying eagle.
Former Senior four wings each,
All things are full of eyes in front and in back,
Always awake sleeping unawares
Conversely holy three times crying constantly,
They, who was, is, and who is to come.
Glory, glory, wisdom
To the Lamb, as he sat on the throne in the heavens;
Reigns with the Father, and with the Holy Spirit,
Connected together three one Deity,
Forever and ever.
Amen.
