(6) ad Marciam de consolatione: written to console Marcia, the daughter of Cremutius Cordus, for the death of her son Metilius. The work may have been written in A.D. 41, as Caligula’s name is studiously avoided.
(7) ad Gallionem de vita beata. This book, addressed to Seneca’s brother Gallio (Novatus), was probably written shortly after A.D. 58, and justifies his having wealth though a philosopher.
(8) ad Serenum de otio. This work, like the next, was addressed to Annaeus Serenus, and was written probably about A.D. 62. Only a part of it is extant. The book discusses whether a wise man should engage in state affairs.
(9) ad Serenum de tranquillitate animi, probably written soon after Seneca’s recall.
(10) ad Paulinum de brevitate vitae. For the date cf. 13, 8, ‘Sullam ultimum Romanorum protulisse pomoerium.’ Now, Claudius extended the pomoerium in A.D. 50, so this must have been written in A.D. 49, as the book was brought out after Seneca’s return from exile.
(11) ad Polybium de consolatione. This book was addressed in A.D. 43 or 44 to Polybius, a favourite of Claudius, on the occasion of his brother’s death. The date is fixed by the reference to Claudius’ expedition to Britain in 12, 2-3. Cf. § 3, ‘Non desinam totiens tibi offerre Caesarem. Illo moderante terras et ostendente, quanto melius beneficiis imperium custodiatur quam armis, illo rebus humanis praeside non est periculum, ne quid perdidisse te sentias.’ For similar flattery of Claudius, cf. 7,4; 12,5.
(12) ad Helviam matrem de consolatione, written during his banishment.
2. ad Neronem Caesarem de clementia, in three Books, two of which are extant. The work was written in A.D. 55-6, doubtless to show the public what sort of instruction Seneca had given Nero, and what sort of emperor they had to expect (cf. i, 1, 1). The date is settled by i. 9, 1, ‘[divus Augustus] cum hoc aetatis esset quod tu nunc es, duodevicesimum egressus annum,’ Nero having been born 15th December, A.D. 37. The flattery contained in ii. 1, 1-2, and elsewhere, can be justified to some extent by Nero’s conduct at that time. Cf. Sueton. Nero, 10, ‘Neque liberalitatis, neque clementiae, ne comitatis quidem exhibendae ullam occasionem omisit.’
3. De Beneficiis in seven Books, addressed to Aebutius Liberalis of Lugdunum. It is probable that Books i.-iv. were published first, shortly after the death of Claudius (who is sneered at in i. 15, 6). Books v.-vii. are probably a later addition. Cf. v. 1, 1, ‘In prioribus libris videbar consummasse propositum ... Quidquid ultra moror, non servio materiae, sed indulgeo ... Verum quia ita vis, perseveremus peractis.’ The eulogy of Demetrius the Cynic in vii. 8-12, makes it probable that Book vii. at least was written in Seneca’s last years.
4. Apocolocyntosis, a political satire on Claudius, written shortly after his death in A.D. 54. The explanation of the title is given by Dio, lx. 35, 2, Ἀγριππίνα καὶ ὁ Νέρων ... ἐς τὸν οὐρανὸν ἀνήγαγον ὃν ἐκ τοῦ συμποσίου φοράδην ἐξενηνόχεσαν. ὅθευπερ Λούκιος Ἰούνιος Γαλλίων ὁ τοῦ Σενέκα ἀδελφὸς ἀστειότατόν τι ἀπεφθέγξατο· συνέθηκε μὲν γὰρ καὶ ὁ Σενέκας σύγγραμμα, ἀποκολοκύντωσιν αὐτὸ ὥσπερ τινὰ ἀπαθανάτισιν ὀνομάσας, ἐκεῖνος δὲ ἐν βραχυτάτῳ πολλὰ εἰπὼν ἀπομνημονεύεται ... ἔφη τὸν Κλαύδιον ἀγκίστρῳ ἐς τὸν οὐρανὸν ἀνενεχθῆναι. The work does not bear this title in the MSS., and there is no hint of the witticism in the book itself; the St. Gall MS., however, has ‘Divi Claudii ΑΠΟΘΗΟΣΙΣ Annei Senecae per Saturam,’ which may be a corruption of the proper title. The title is derived from κολοκύντη, ‘a gourd,’ which was used to denote a fool. Seneca (Apocol. 6) takes the official view that Claudius died of a fever. The work may have been published at the Saturnalia, and written shortly before, as Narcissus is represented as having just arrived in Orcus. The personal animosity of Seneca against Caligula and Claudius is everywhere apparent.
