like Gellius, bases his work
on extracts from older authorities; but, unlike him, arranges his
matter systematically.

5. AELIUS DONATUS, a grammarian who flourished at Rome about A.D. 350,
and was one of Jerome's teachers, extracted from the lost work of
Suetonius the Lives of Terence and Virgil, and prefixed them to his
own commentaries on Terence and on the _Georgics_ and _Aeneid_. The
latter is lost, and the commentary on Terence contains much that is
not from the hand of Donatus.

6. SERVIUS.--There are two versions of the Servian commentary on
Virgil. The shorter is the work of Maurus Servius Honoratus, who was
born about 350 A.D., and lived at Rome (Macrob. _Saturn._ i. 2, 15);
his topographical references show that he composed his commentary
there. Servius, whose notes are chiefly on the language of the poems,
gives illustrative quotations from Roman authors, in some cases from
memory and inaccurately. Donatus is the authority whom he mentions
oftenest, but he undoubtedly made extensive use of Suetonius.

The longer version contains learned additions to the work of Servius
by an anonymous Christian writer, who deals mainly with the
subject-matter of Virgil.

7. ACRO and PORPHYRIO.--Helenius Acro (probably about 200 A.D.) was
the author of commentaries on Horace and Terence, now lost. The
scholia on Horace extant under Acro's name are, with few exceptions,
taken from the commentary of Pomponius Porphyrio, which we possess in
a mutilated form. Porphyrio, who probably belonged to the 4th cent.
A.D., names among his sources Acro and Suetonius.
