Lactantii Placidi In Statii Thebaida commentum. Volumen I. Anonymi In Statii Achilleida commentum. Fulgentii ut fingitur Planciadis Super Thebaiden commentariolum, recensuit R. D. Sweeney, Stutgardiae et Lipsiae 1997 (Bibliotheca Scriptorum Graecorum et Romanorum Teubneriana).

Only two manuscripts report this text: Paris, Bibliothèque Nationale, lat. 3012, 60v-54r (end of the 12^th - beginning of the 13^th c.) and Bern, Bibl. Mun. MS 141, 323, which was copied by the French humanist Pierre Daniel and dated to around 1600 AD by Robert Sweeney; the latter scholar discovered this second codex and held it to be a direct copy of the first.  The text was initially attributed to Fulgentius of Ruspe (467-533 AD) on the basis of a title in the Parisian manuscript (Sancti Fulgencii Episcopi super Thebaiden), but most critics now reject this attribution.  As a result, its late-antique origin is now also open to debate, with many facts actually supporting a date between 1100 and 1300 AD, a period in which much exegetical material on the Thebaid was produced.  Stock has been more precise, asserting that the text’s accessus displays important etymological affinities with similar commentaries on Statius that date to the 12^th century.  [A. Borgna; tr. C. L. Caterine].
