VIBIUS SEQUESTER (4th or 5th century, A.D.), the supposed author of an alphabetical list of geographical names occurring in the Roman poets, with special reference to Virgil, Ovid and Lucan. Several of the names given cannot be traced; unless this is the result of carelessness or ignorance, the compiler must have had access to sources no longer extant. Editions by C. Bursian (Zurich, 1867), and in A. Riese, Geographi Latini minores (1878); see also Teuffel, Hist. of Roman Literature (Eng. trans., 1900), 445, 1.
