Somewhat later than Trajan was Siculus Flaccus (De condicionibus agrorum, extant), while the most curious treatise on the subject, written in barbarous Latin and entitled Casae litterarum (long a school textbook) is the work of a certain Innocentius (4th-5th century).
Shortly afterwards he held a council in Auvergne, to adjust the dispute which had arisen between two of his suffragans, Innocentius, Bishop of Rodez, and Ursicinus, Bishop of Cahors, with regard to parishes for which they contended.
