Claudius Aelianus (Ancient Greek: Κλαύδιος Αἰλιανός, modern Greek transliteration Klávdios Elianós; c. 175 – c. 235 AD), commonly Aelian (), born at Praeneste, was a Roman author and teacher of rhetoric who flourished under Septimius Severus and probably outlived Elagabalus, who died in 222. He spoke Greek so fluently that he was called "honey-tongued" (μελίγλωσσος meliglossos); Roman-born, he preferred Greek authors, and wrote in a slightly archaizing Greek himself.
His two chief works are valuable for the numerous quotations from the works of earlier authors, which are otherwise lost, and for the surprising lore, which offers unexpected glimpses into the Greco-Roman world-view. It is also the only Greco-Roman work to mention Gilgamesh.
On the Nature of Animals ("On the Characteristics of Animals" is an alternative title; Ancient Greek: Περὶ ζῴων ἰδιότητος, Perì zṓōn idiótētos; usually cited, though, by its Latin title: De Natura Animalium) is a curious collection, in seventeen books, of brief stories of natural history, sometimes selected with an eye to conveying allegorical moral lessons, sometimes because they are just so astonishing:
Aelian's anecdotes on animals rarely depend on direct observation: they are almost entirely taken from written sources, often Pliny the Elder, but also other authors and works now lost, to whom he is thus a valuable witness. He is more attentive to marine life than might be expected,[according to whom?] though, and this seems to reflect first-hand personal interest; he often quotes "fishermen". At times he strikes the modern reader as thoroughly credulous, but at others he specifically states that he is merely reporting what is told by others, and even that he does not believe them. Aelian's work is one of the sources of medieval natural history and of the bestiaries of the Middle Ages.
The portions of the text that are still extant are badly mangled and garbled and replete with later interpolations. Conrad Gessner (or Gesner), the Swiss scientist and natural historian of the Renaissance, made a Latin translation of Aelian's work, to give it a wider European audience. An English translation by A. F. Scholfield has been published in the Loeb Classical Library, 3 vols. (1958-59).
Various History (Ποικίλη ἱστορία, Poikílē historía)—for the most part preserved only in an abridged form—is Aelian's other well-known work, a miscellany of anecdotes and biographical sketches, lists, pithy maxims, and descriptions of natural wonders and strange local customs, in 14 books, with many surprises for the cultural historian and the mythographer, anecdotes about the famous Greek philosophers, poets, historians, and playwrights and myths instructively retold. The emphasis is on various moralizing tales about heroes and rulers, athletes and wise men; reports about food and drink, different styles in dress or lovers, local habits in giving gifts or entertainments, or in religious beliefs and death customs; and comments on Greek painting. Aelian gives an account of fly fishing, using lures of red wool and feathers, of lacquerwork, serpent worship — Essentially the Various History is a Classical "magazine" in the original senses of that word. He is not perfectly trustworthy in details, and his agenda was heavily influenced by Stoic opinions, perhaps so that his readers will not feel guilty, but Jane Ellen Harrison found survivals of archaic rites mentioned by Aelian very illuminating in her Prolegomena to the Study of Greek Religion (1903, 1922).
The first printing was in 1545. The standard modern text is Mervin R. Dilts's, of 1974.
Two English translations of the Various History, by Fleming (1576) and Stanley (1665) made Aelian's miscellany available to English readers, but after 1665 no English translation appeared, until three English translations appeared almost simultaneously: James G. DeVoto, Claudius Aelianus: Ποικίλης Ἱστορίας (Varia Historia) Chicago, 1995; Diane Ostrom Johnson, An English Translation of Claudius Aelianus' "Varia Historia", 1997; and N. G. Wilson, Aelian: Historical Miscellany in the Loeb Classical Library.
Considerable fragments of two other works, On Providence and Divine Manifestations, are preserved in the early medieval encyclopedia, the Suda. Twenty "letters from a farmer" after the manner of Alciphron are also attributed to him. The letters are invented compositions to a fictitious correspondent, which are a device for vignettes of agricultural and rural life, set in Attica, though mellifluous Aelian once boasted that he had never been outside Italy, never been aboard a ship (which is at variance, though, with his own statement, de Natura Animalium XI.40, that he had seen the bull Serapis with his own eyes). Thus conclusions about actual agriculture in the Letters are as likely to evoke Latium as Attica. The fragments have been edited in 1998 by D. Domingo-Foraste, but are not available in English. The Letters are available in the Loeb Classical Library, translated by Allen Rogers Benner and Francis H. Fobes (1949).
