Suetonius, On Famous Men

Portrait of a Roman official, first quarter of the second century (Koninklijke Musea voor Kunst en Geschiedenis, Brussel)

Suetonius is best known for the Lives of the Twelve Caesars, but that is just a part of his oeuvre, which also included such titles as Physical Defects of Men, Greek Children’s Games, Lives of Famous Prostitutes, and a dictionary that contained only terms of abuse. The twenty books of the Playground of Names and Languages culminated in a series of biographies of

• Latin poets like Horace, Lucan, Persius, Terence, Tibullus, Virgil (book 15),
• playwrights (book 16),
• orators (book 17),
• grammarians and rhetoricians (book 18),
• historians (Pliny the Elder) and philosophers (book 19).

Fragments survive, most of them rather short (like Passienus Crispus) but some of them still pretty long. They are now available at LacusCurtius: go here, or use one of the links above. You can find both the Latin texts and the Loeb translation.
