Some Favorites
Two of my favorite scholars that I've been reading recently on Late Antiquity are Alan Cameron and Robert Kaster. Their writings are models of careful, well-documented scholarship, presenting interesting ideas in a lucid and clearly-argued fashion.
Two absolutely wonderful articles by Prof. Cameron on Macrobius, inter alia, are:
'The Date and Identity of Macrobius', JRS 56 (1966) 25-38
'Macrobius, Avienus, and Avianus', CQ 17 (1967) 385-99
Prof. Kaster has written, in addition to his monumental study on the Late Antique grammarian entitled Guardians of Language, a number of other fascinating articles on Late Antique education and literary culture. See, for example:
'The Grammarian's Authority', CP 75 (1980) 216-41
'Macrobius and Servius: Verecundia and the Grammarian's Function', HSCP 84 (1980) 219-62
'Notes on "Primary" and "Secondary" Schools in Late Antiquity', TAPA 113 (1983) 323-46
'Servius and Idonei Auctores', AJP 99 (1978) 181-209
If you have access to JStor, all of these articles can be found there.
