Previously, I asked for suggestions for an essential reading list of secondary sources on the ancient world. Here's what we've got so far:
Bing, Peter. The Well-Read Muse.
Buck, Carl Darling. The Greek Dialects.
Burkert, Walter. Greek Religion.
Dill, Samuel. Roman Society from Nero to Marcus Aurelius.
Dodds, E.R. The Greeks and the Irrational.
Finley, M.I. The Ancient Economy.
Frazer, James. The Golden Bough.
Gibbon, Edward. The Decline and Fall of the Roman Empire.
Guthrie, W.K.C. A History of Greek Philosophy.
Harrison, Jane Ellison. Prolegomena to the Study of Greek Religion.
Heinze, Richard. Virgil's Epic Technique.
Jaeger, Werner. Paideia.
Lord, A.B. The Singer of Tales.
Meiggs, R., and D. Lewis, A selection of Greek historical inscriptions to the end of the fifth century B.C.
Nagy, Gregory. The Best of the Achaeans.
Pickard-Cambridge, A.W. Dithyramb, Tragedy And Comedy (the original of 1927, not T.B.L. Webster's 1962 update).
Pickard-Cambridge, A.W. Dramatic Festivals of Athens.
Sandys, John Edwin. A History of Classical Scholarship.
Snell, Bruno. The Discovery of the Mind.
Syme, Ronald. The Roman Revolution.
Vermeule, Emily. Greece in the Bronze Age.
Wilamowitz. History of Classical Scholarship (tr. Hugh Lloyd-Jones).
Wilkinson, L.P. Golden Latin Artistry.
Williams, Bernard. Shame and Necessity.
Thanks to everyone for some great suggestions. I think we can still do a little more, though. If anyone has recommendations for histories or handbooks of Greek and Latin literature (for example, I have some familiarity with Lesky for Greek lit. and Conte for Latin; perhaps I'll add those) or meter (both Greek and Latin--preferably something that would be understandable for undergraduates; perhaps Halporn/Otswald/Rosenmeyer?), please please please drop them in the comments box.
