C. J. Fordyce (ed.), Catullus: A Commentary
Mentula here and in 94, 114, and 115 has generally been taken to be an offensive nickname for Caesar's favourite officer Mamurra (see 29 int.), who appears under his own name in 29 and 57. His literary pretensions are ridiculed again in 57. 7 where he and Caesar are uno in lectulo erudituli ambo.
105. 1 pipileium V: corr. R
scindere V: corr. ζ
1. Pipleium … montem : the hill of the Muses in Pieria, where the spring Pipla and the region about it, on the northern foothills of Olympus, were sacred to them: so the Muse is Piplea (or Pipleis) in Hor. Od. i. 26. 9. For the aspirant to poetry represented as climbing the Muses' hill cf. Ennius, Ann. 215 V. 'neque Musarum scopulos ‹quisquam superarat›'.
2 furcilis V: corr. R
2. furcillis … eiciunt : for the proverbial expression cf. Hor. Ep. i. 10. 24 'naturam expelles furca, tamen usque recurret', Cic. Att. xvi. 2. 4 'quoniam furcilla extrudimur, Brundisium cogito'.
