This landmark book explores the ways in which the Greco-Roman tradition has shaped modern European and American literature.
This book is truly excellent (1) for the list of influential writers in all ages that he had himself hand selected (I've never heard of Abraham a Santa Clara and now I'm itching for a translation), and most importantly, (2) because it gives the necessary cultural backdrop that anchors a given author to an era with all its advantages and limitations. For example, the book gives a reason why the Augustan poets (Dryden, Pope and friends) were driven to mincing affectations (partly a reaction to the Renaissance, partly a particularly Baroque censorship of vulgar words that comes from a misunderstanding of the classics. Highet provides some choice sample of Juvenal's trenchant and vulgar satires as a counterexample).
