The commentaries on
Virgil's
Aeneid, , , , or survive in two distinct manuscript traditions. The first is a comparatively short commentary, attributed to Servius in the superscription in the manuscripts and by other internal evidence. The second class derive from the 10th and 11th centuries, embed the same text in a much expanded commentary. The copious additions are in contrasting style to the original; none of these manuscripts bears Servius' name, and the commentary is known traditionally as
Servius auctus or
Servius Danielis, from Pierre Daniel who first published it in 1600. "The added matter is undoubtedly ancient, dating from a time but little removed from that of Servius, and is founded to a large extent on historical and antiquarian literature which is now lost. The writer is anonymous and probably a Christian", although one proposed author,
Aelius Donatus, was a Christian. A third class of manuscripts, written for the most part in Italy, includes the core text with interpolated
scholia, which demonstrate the continued usefulness of the
Virgilii Opera Expositio. ==Other works==
