[Sidenote: Nonius. Macrobius. Martianus Capella.] In the early years of the century Nonius Marcellus, a Peripatetic philosopher of Thubursicum, in Numidia, wrote for his son a work in twenty books, _De Compendiosa Doctrina_, in which he discusses many questions pertaining for the most part to early Latin literature. This work is modelled on the _Noctes Atticæ_ of Gellius, to which it is vastly inferior. It is nevertheless of value as our only authority for the titles of some lost works and even for extracts from them. For similar reasons the _Saturnalia_, in seven books, by Ambrosius Theodosius Macrobius, is of some importance. Macrobius, who was probably, like Nonius, an African, appears to be identical with the Macrobius who was proconsul of Africa in 410 A. D, The imaginary conversations of which his _Saturnalia_ consists treat of Roman literature and antiquities, especially of the poetry of Virgil. Like Gellius and Nonius, Macrobius uses the works of earlier critics and commentators, and gives many quotations from Greek and Roman authors. Macrobius also wrote a commentary on Cicero’s _Dream of Scipio_, in which he quotes many authors, especially Greeks, but displays little or no originality. The encyclopædia, in nine books, written about the end of the fourth century by a third African, Martianus Capella, is of less value than
