Expositio totius mundi et gentium ("A description of the world and its people") refers to a brief "commercial-geographical" survey written by an anonymous citizen of the Roman Empire living during the reign of Constantius II. The Greek original, composed between AD 350-362, is now lost, but comes to us through two Latin translations made during the sixth century.
Contents
The work is composed of three parts. The first (§ 1-21) describes lands east of the Roman Empire and contains the most legendary and least accurate geographical information. The second part (§ 22-62), the longest, describes the mainland provinces of the Empire, while the third (§ 63-68) describes island provinces.
The anonymous author
Little is known about the anonymous author of the work, though clues from the text are often used to garner information. While "it has been suggested that he was a rhetor, sophist, merchant, enterpreneur [sic] or a vir rusticus", the work's preoccupation with trade and port cities is notable. He mentions 61 cities, only 16 of which are in the western portion of the Empire. It is usually assumed he was a native of Syria.
The author's religion is likewise a mystery. While he mentions numerous Greek writers (Berossus, Manetho, Apollonius, Menander of Ephesus, Herodotus and Thucydides), he shows little sign of any real influence by them, or indeed of any meaningful education, possibly only being aware of them through his familiarity with Against Apion by Josephus, whom he refers to as the "teacher of the Jews".
On the one hand, Josephus is more likely to have been known to a Christian. The text also contains "Biblical allusions" and "Christian phrases". However, the text shows no interest in the churches or holy sites documented by the later Christian itineraria, and is more likely to note a city's "gripping games, good wines and pretty women", while displaying an "obvious affinity" to pagan cults and rituals.
Latin translations
One of the surviving translations, from which the more well known title of Expositio totius mundi is derived, is now also lost but was preserved by Jacques Godefroy's 1628 printing of its text. The other, from a manuscript held in a Benedictine monastery in Cava, near Naples, was published in 1831 by Angelo Mai and bears the title Descriptio totius mundi. The Descriptio, while more abridged than the Expositio, is nonetheless the only manuscript to contain the beginning of the work.
Both manuscripts are printed in Karl Müller's Minor Greek Geographers (1861). An English translation, now available online, was made by Jesse Woodman as part of a Master's thesis at Ohio State University in 1964. A widely available printed English translation has never been published.
