AVIENUS, RUFUS FESTUS, a Latin poet, who appears to have flourished in the latter half of the fourth century. He is the author of the following works:—1. Descriptio Orbis Terra, sometimes called Metaphrasis Periegeseos Dionysii, being derived from the περιήγησις of that writer; 2. Ora Maritima; 3. Aratea Phenomena, and Aratea Prognostica, which are paraphrases of two works of Aratus. These poems, with the exception of the last two, are contained in Wernsdorf's Posta Latini Minores, vol. v. pt. ii.
