II.
Aeterna Christi numera, et martyrum, Illuminans altissimus, Orabo mente dominum, (from Bis ternas horas,) Splendor paternae gloriae.
These are the probable hymns.
III.
Apostolorum passio, Conditor alme siderum, Consors paterni luminis, Hic est dies verus Dei, Jam lucis orto sidere, Nunc sancte nobis Spiritus, O lux beata Trinitas, Obduxere polum nubila coeli, O rex aeterne domine, Rector potens, verax Deus, Rerum Deus tenax vigor, Somno refectis artubus, Squalent arva soli pulvere multo, Summae Deus clementiae, Tristes erant apostoli.
These have, for one reason or another, been assigned to Ambrose. It is to be remembered that the Tristes erant is a part of the Aurora lucis rutilat, and that in many cases the hymns are very much intermingled. A rigid designation is therefore impossible. The fourth class comprehends what may be called Ambrosiani—the Sedulian and Gregorian and other hymns being simply excluded from the list.

While these are often known to be mere paraphrases of Ambrose’s own homilies, or imitations of his hymns, they are as frequently found to possess his spirit and almost the very forms of his verse. Thus Daniel says of the Ter hora trina that it is “not unworthy of Ambrose himself.” We also find many cases where the Roman Breviary has altered the first line as well as changed the arrangement of the stanzas.
The last class are those hymns, formerly called Ambrosian, but now known to be the work of other hands. They are given with their authors’ names appended.
