 West argues that the four lines missing from the Cologne papyrus were part of a separate poem , though Lardinois comments that there is no evidence in the Oxyrhynchus papyrus to confirm or deny this . However , other scholars , including Gronewald and Daniel , who originally published the Cologne fragments , believe that the poem did continue for these four lines . Lardinois suggests that there may have been two versions of the poem current in antiquity , one ending after the twelfth line , the other continuing to line 16 . Gregory Nagy agrees , arguing that the two versions were appropriate for different performance contexts .
