Fabius Dorsennus (also spelled Dossennus or Dossenus) was a thespian and author of Atellan Farce in Ancient Rome, known for his careless performances. According to Seneca his epitaph was: "Halt, stranger, and understand Dossennus' wisdom".
There is some confusion regarding this figure from ancient Roman theater. In one of his epistles, Horace mentions a Dossennus:
[He] exceeds all measure in his voracious parasites; with how loose a sock he runs over the stage: for he is glad to put the money in his pocket, after this regardless whether his play stand or fall.— Book II, Epistle I
Fabius Dossennus quite decides the question, in the following line—; 'I sent them good wine, myrrh-wine'; and in his play called Acharistio, we find these words: 'Bread and pearled barley, myrrh-wine too.'
