The difference of authorship of _Ecl._ 1-7 and of _Ecl._ 8-11 is shown by the following: (1) Final _ŏ_ shows classical usage in 1-7, but in 8-11 we have _expectŏ_ (9, 26), _coniungŏ_ (10, 14), _ambŏ_ (9, 17), and the like; (2) 1-7 show only eight elisions, 7-11 show thirty-nine; (3) no ending like _montivagus Pan_ (10, 17) is found in 1-7; (4) _fateor_ and _memini_ used parenthetically are common in 1-7, and not found in 8-11; (5) there are no allusions to the emperor in 8-11; (6) _Ecl._ 9 shows imitations of _Ecl._ 2 and 3; (7) 8-11 agree in many points with Nemesianus' _Cynegetica_. The _Eclogues_ are modelled chiefly on Virgil and Theocritus, _e.g._ _Ecl._ 3 on Verg. _Ecl._ 7 and Theocr. 3, 14, and 23. The poem _de laude Pisonis_ is now generally attributed to Calpurnius Siculus. One point of similarity with Calpurnius' other poems is the rareness of elision, there being only two instances (ll. 24, 259). The description of Piso's liberality and eloquence (ll. 32, 88, 97 _sqq._) and of his skill in draughts (ll. 178-96) corresponds with the information given by Tac. _Ann._ xv. 48 and the Schol. on Iuv. 5, 109, about Calpurnius Piso, who flourished under Claudius. AETNA. This poem, in 645 hexameter lines, is attributed to Virgil in the MSS., but is probably by Lucilius Iunior, to whom Seneca addresses his _Epistulae Morales_, _De Providentia_, and _Quaestiones Naturales_. Lucilius was younger than Seneca (Sen. _Ep._ 26, 7, 'iuvenior es'), and was born at Naples or Pompeii. Sen. _Ep._ 49, 1, 'Ecce Campania et maxime Neapolis ad Pompeiorum tuorum conspectum incredibile est quam recens desiderium tui fecerint.' Lucilius had held procuratorial offices in Alpes Graiae et Poeninae, Epirus, Creta et Cyrene, and Sicily. _Ibid._ 44, 2, 'Eques Romanus es et ad hunc ordinem tua te perduxit industria.' _Ibid._ 31, 9, 'Quo modo, inquis, isto pervenitur? Non per Poeninum Graiumve montem, nec per deserta Candaviae, nec Syrtes tibi nec Scylla aut Charybdis adeundae sunt, quae tamen omnia transisti procuratiunculae pretio.'[80] Sen. _N.Q._ iv. praef. 1, 'Delectat te, Lucili, Sicilia et officium procurationis otiosae.' For his life cf. also the words put into his mouth by Sen. _N.Q._ iv. praef. 15-17, which show his loyalty to his friends, 'Non mihi in amicitia Gaetulici (died A.D. 39) vel Gaius fidem eripuit, non in aliorum persona infeliciter amatorum Messalla et Narcissus ... propositum meum avertere potuerunt ... videbam apud Gaium tormenta, videbam ignes.'[81] Seneca speaks of him as a pupil in philosophy in _Ep._ 34, 2, 'Adsero te mihi: meum opus es.' A literary work of his is spoken of by Seneca, also a poem in which he mentions Alpheus and Arethusa: _Ep._ 46, 1, 'Librum tuum, quem mihi promiseras, accepi. Levis mihi visus est, cum esset nec mei nec tui corporis, sed qui primo adspectu aut T. Livi aut Epicuri posset videri ... Non tantum delectatus, sed gavisus sum.'
