Description: The perfection of the 5-part writing has been interpreted as suggesting that the sextus was added later, possibly by a different composer. Brussels 9126 has a 4vv version lacking both sextus & tenor, yet performable with only very slight awkwardness.
Original text and translations
Huc me sydereo descendere jussit Olympo
hic me crudeli vulnere fixit amor.
Langueo nec quisquam nostro succurrit amori
quem nequeunt dure frangere jura crucis.
Pungentem capiti Dominum gestare coronam
fortis amor docuit verbera tanta pati.
Felle sitim magni regis satiavit amaro
pectus ut hauriret lancea fecit amor.
De me solus amor potuit perferre triumphum
ille pedes clavis fixit et ille manus.
Si cupis ergo animi mihi signa rependere grati
dilige pro tantis sat mihi solus amor.
Tenor: Plangent eum quasi unigenitum quia innocens Dominus occisus est.
Here love ordered me to come down from starry Olympus,
And struck me with a cruel wound.
I languish, and none comes to help my love,
Which the harsh law of the Cross cannot break.
Strong love taught the Lord to wear the piercing crown on his head,
To suffer such blows.
Love satisfied the thirst of your great King with bitter gall,
And caused the lance to drain his breast.
Love alone was able to triumph over me;
It pierced my hands and feet with nails.
If, therefore, you wish to repay me with the signs of a grateful spirit,
Love that above all which alone can satisfy me: love.
Tenor: They weep for him as for an only son, for the innocent Lord has been killed.
