 Scholars disagree about how this should be interpreted . André Lardinois lists possible explanations which have been put forward : firstly that the Cologne papyrus did not contain the full poem , but only the first twelve lines ; secondly that the poem does end after line twelve and the final lines on the Oxyrhynchus papyrus were part of another poem ; and thirdly that there were two different endings for the poem , one at line twelve and one continuing on to line sixteen .
