High Quality Content by WIKIPEDIA articles! The Panegyrici Latini or Latin Panegyrics is a collection of twelve ancient Roman panegyric orations. The authors of most of the speeches in the collection are anonymous, but appear to have been Gallic in origin. Aside from the first panegyric, composed by Pliny the Younger in 100 CE, the other speeches in the collection date to points between 289 and 389 CE. The original manuscript, discovered in 1433, has perished; only copies remain.
