Under Diocletian and his successors there was a slight and partial revival of letters, which chiefly showed itself on the side of verse. The _Cynegetica_, a didactic poem on hunting, by the Carthaginian poet Marcus Aurelius Olympius Nemesianus, is, together with four bucolic pieces by the same author, the chief surviving fragment of the main line of Virgilian tradition. The _Cynegetica_, in spite of its good taste and its excellent versification, is on the whole a dull performance; but in the other pieces, the pastoral form gives the author now and then an opportunity of introducing a little touch of the romantic tone which is partly imitated from Virgil, but partly natural to the new Latin. _Perdit spina rosas nec semper lilia candent Nec longum tenet uva comas nec populus umbras, Donum forma breve est, nec se quod commodet annis:--_ in these graceful lines the copied Virgilian cadence is united with the directness and the real or assumed simplicity which belongs to the second childhood of Latin literature, and which is so remarkable in the authors who founded the new style. The new style itself was also largely practised, but only a few scattered remnants survive. Tiberianus, Count of Africa, Vicar of Spain, and praetorian prefect of Gaul (the whole nomenclature of the Empire is now passing from the Roman to the mediaeval type) under Constantine the Great, is usually identified with the author of some of the most strikingly beautiful of these fragmentary pieces. A descriptive passage, consisting of twenty lines of finely written trochaics, reminds one of the _Pervigilium Veneris_ in the richness of its language and the delicate simplicity of its style. The last lines may be quoted for their singular likeness to one of the most elaborately beautiful stanzas of the _Faerie Queene_, that which describes the sounds "consorted in one harmony" which Guyon hears in the gardens of Acrasia:-- _Has per umbras omnis ales plus canora quam putes Cantibus vernis strepebat et susurris dulcibus: Hic loquentis murmur amnis concinebat frondibus Quas melos vocalis aurae, musa Zephyri, moverat: Sic euntem per virecta pulcra odora et musica Ales amnis aura lucus flos et umbra iuverat._
