Nonnus. His Dionysiaca are not yet given in a good edition. There are two unfinished editions probably yet in progress, that began to appear at Heidelberg and Leipsig, in 1819. The first is by Moser, as yet of only the 6 books from the 8th to the 13th. The other, by Græfe, contains the first 24 books, 1 vol. the text alone.
Nonnius Marcellus is confined to grammatical subjects.
Julius Obsequens. His de Prodigiis may be safely omitted.
Ocellus Lucanus. His Fragments are neither important, nor of a clear authenticity.
Oppian, de Venatione et Piscatu. If purchased, the best edition is that of Schnieder, Leipsig, 1813, 8vo. It should, however, when bought, be given to some genius vast enough to embrace both the arts of Industry and those of Indolence.
Oratores Græci, à Reiske. Lipsiæ, 1770, 8 vols. in 12, 8vo. It brings 220 francs, entire. The latter 6 volumes may sometimes be had separate; and these, united with the London re-edition of Reiske's Demosthenes [1822, 3 vols. 8vo.] and the Isocrates of Coray, give the proper series of Orators.
Orphæus, Argonautica, &c. cum notis variorum, àb Hermanno. Lipsiæ, 1805, 8vo. 20 francs. It contains the discussion as to the age and author of the Orphica; a dispute set on foot by Huet, whose opinion Valcknaer, Schnieder and Hermann have since maintained; while the genuineness of the Poems has been supported by Gesner, Ruhnken and some others.
Ovid. Burmann's is no doubt the best edition; but is in 4to. and high priced—8l. 8s. The best 8vo. edition, notis variorum, is that of Cnipping, Leyden, 1670, 3 vols. 45 frs.
Palæphatus. His Incredibilia are only proper for a mythographic collection.
Palladius, de Febribus may, of course, be omitted.
