 Shortly before 1500, Catullus 3 (the lament) was separated from Catullus 2/2b by Marcantonio Sabellico, which has been supported by scholars ever since.Scholars have argued over whether the last three lines (2b) belong to a different poem, and whether words are missing between poems 2 and 2b.Scholars suggest that missing words (a "lacuna"), or a variant reading/rearrangement of the received text, would smooth the presently abrupt transition between lines 10 and 11.
