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.
