This is a very significant book: the editio princeps (first appearance in print) of Sophocles' Seven Tragedies: Ajax, Electra, Oedipus Rex, Antigone, Oedipus at Colonus, The Women of Trachis, and Philoctetes. It is also important as the first Greek text printed in octavo format, as part of Aldus' libelli portatiles. This features Aldus' fourth Greek typeface. The preface suggests that this book includes a commentary, but that didn't appear until a 1518 edition. The Anchor & Dolphin device appears on p 396.
