This article presents in concise but comprehensive fashion the work that led to the identification of the text contained in P.Herc. 1067 as the historical work of Seneca the Elder. After a brief overview of the history of Herculaneum studies,the paper focuses on the new reading of the first line of the subscriptio, which,by allowing us to identify the author as a Lucius Annaeus Seneca, has shown the previous attribution of the text to Lucius Manlius Torquatus, and accordingly its interpretation as an oratio in Senatu habitaante principem, to be incorrect. There follows a description of the roll in bibliological, palaeographical and papyrological terms, as well as a brief presentation of its contents. They are elucidated using the prosopography contained in the papyrus which wholly refers to the Augustan or Tiberian age. The article closes with a detailed description of the second line of the subscriptio which contains the title of the work.
