relative clauses become gradually longer in length: quem ludere, quem in sinu tenere, and cui primum digitum dare appetenti et acris solet incitare morsus. The repeated "eee" sounds (corresponding to the letter "i" in Latin) evoke the songbird's peeping (pipiabat in Catullus 3), e.g., (quicum ... in sinu ... cui primum ... appetenti ... acris ... nitenti ... iocari). The "a" sounds may also convey images: the poet's sighs of longing; an "ouch!" at being bitten sharply (appetenti, "pecking" and acris, "sharp"); and a comforting sound (solaciolum, "small comfort", and acquiescat, "calms"). Influence on later poetry This poem and the following Catullus 3 (a lament for Lesbia's sparrow) inspired a genre of poems about lovers' pets. One classical example include Ovid's elegy on the death of his mistress Corinna's parrot (Amores 2.6.). Another is Martial's epigram (Book I number CIX) on a lap dog, which refers to Catullus 2 specifically ("Issa est passere nequior Catulli", "Issa [the dog] is naughtier than Catullus's sparrow"). Following the printing of Catullus's works in 1472, Poems 2 and 3 gained new influence. From the earliest days after the re-discovery of Catullus' poems, some scholars have suggested that the bird was a phallic symbol, particularly if sinu in line 2 is translated as "lap" rather than "bosom". Other scholars, however, have rejected this suggestion. Birds were common love-gifts in the Classical world, and several scholars have speculated that the narrator gave it to the woman; this might explain the poet's identification with the sparrow and his fond lament for the bird in Catullus 3. The biting it does in line 4 ties in with Catullus 8, line 18 (cui labella mordebis). Manuscript tradition A key question concerns the unity of this poem. In the copies derived from the original V manuscript, poems 2 (lines 1–10 below), 2b (lines 11–13 below), and Catullus 3 appear as one poem under the title "Fletus passeris Lesbie" (Lament for Lesbia's Sparrow). 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. As noted above, there
