as the swallow song of Rhodes). Food and wine, luxury, music, sexual mores, literary gossip and philology are among the major topics of discussion, and the stories behind many artworks such as the Venus Kallipygos are also transmitted in its pages. Food and cookery The Deipnosophistae is an important source of recipes in classical Greek. It quotes the original text of one recipe from the lost cookbook by Mithaecus, the oldest in Greek and the oldest recipe by a named author in any language. Other authors quoted for their recipes include Glaucus of Locri, Dionysius, Epaenetus, Hegesippus of Tarentum, Erasistratus, Diocles of Carystus, Timachidas of Rhodes, Philistion of Locri, Euthydemus of Athens, Chrysippus of Tyana, Paxamus and Harpocration of Mende. It also describes in detail the meal and festivities at the wedding feast of Caranos. Drink In expounding on earlier works, Athenaeus wrote that Aeschylus "very improperly" introduces the Greeks to be "so drunk as to break their vessels about one another's heads": This is the man who threw so well The vessel with an evil smell And miss'd me not, but dash'd to shivers The pot too full of steaming rivers Against my head, which now, alas! sir, Gives other smells besides macassar. Homosexuality In addition to its main focuses, the text offers an unusually clear portrait of homosexuality in late Hellenism. Books XII-XIII holds a wealth of information for studies of homosexuality in Roman Greece. It is subject to a broader discussion that includes Alcibiades, Charmides, Autolycus, Pausanias and Sophocles. Furthermore, numerous books and now lost plays on the subject are mentioned, including the dramatists Diphilus, Cratinus, Aeschylus, and Sophocles and the philosopher Heraclides of Pontus. First patents Athenaeus described what may be considered the first patents (i.e. exclusive right granted by a government to an inventor to practice his/her invention in exchange for disclosure of the invention). He mentions that several centuries BC, in the Greek city of Sybaris (located in what is now southern Italy), there were annual culinary competitions. The victor was given the exclusive right to prepare his dish for one year. Such a thing would have been unusual at the time because Greek society at large did not recognize exclusivity in inventions or ideas. Survival and reception The Deipnosophistae was originally in fifteen books. The work survives in one manuscript from which the whole of books 1 and 2, and some other pages
