Notitia dignitatum omnium, tam civilium quam militarium, in partibus orientis et occidentis, edited by E. Bocking, Bonn, 1839-1853.

This work is an official directory and army list of the Roman Empire, compiled about the end of the fifth century, and was preserved in a (now lost) Codex Spirensis.

Olympiodorus, Ἱστορικοὶ λόγοι, abridgment edited by Ph. Labbé, in his Eclogæ Historicorum de Rebus Byzantinis, included in D. Hoeschelius’ Excerpta de Legationibus, Paris, 1645.

Olympiodorus, a native of Thebes, in Egypt, lived in the fifth century. His history which is preserved only in the abridgment of Photius was in 22 books, and dealt with the Western Empire under Honorius from 407 to 425. It was a compilation of historical material, rather than a history. Olympiodorus wrote a continuation of Eunapius, one of the Byzantine historians.

Origo Gentis Longobardorum, edited by F. Bluhme, in Monumenta Germaniæ Historica, Hanover, 1819, in progress.

The oldest document for the history of the Lombards, prefixed to the code of King Rothari.

Orosius, Paulus, Historiarum adversus Paganos Libri VII: Vienna, 1471; edited by Havercamp, Leyden, 1738; English translation edited by D. Barrington and J. R. Foster, with the Anglo-Saxon, by Alfred the Great, London, 1773.

Paulus Orosius, born probably at Tarrayonce in Spain: lived in the first part of the fifth century, A.D. At the request of the Bishop of Hippo (St. Augustine) Orosius in early manhood compiled a history of the world, remembered partly because Alfred the Great translated it into Anglo-Saxon.

Panegyrici Veteres latine, edited by H. J. Arntzenius, Utrecht, 1790; edited by Bährens, Leipsic, 1874. A collection of eleven complimentary orations delivered at Rome, in praise of different emperors. While these orations are notable examples of rhetorical skill, they are naturally valueless for historical study, being coloured and distorted to suit the occasion.—Paterculus, Caius Velleius, Historiæ Romanæ, ad M. Vinicium Cos. Libri II, Basel, 1520; Leyden, 1789; (translated by J. S. Watson, London, 1861).

Caius Velleius Paterculus, born about 19 B.C.; died after 30 A.D., contemporary with Augustus and Tiberius. The work of Paterculus, apparently the only one he ever wrote, appears to have been written in 30 A.D. The beginning of the work is wanting, and there is also a portion lost after the eighth chapter of the first book. It commenced apparently with the destruction of Troy, and ended with the year 30 A.D.
