1. _Epistulae ad Atticum_, in sixteen Books, belonging to the years B.C. 68-43, and valuable for their thorough frankness (_ad Att._ viii. 14, 2, 'ego tecum tamquam mecum loquor'). Nepos appreciates their supreme importance for the history of Cicero's time, although he dates the commencement of the correspondence wrongly: _Att._ 16, 'xvi. volumina epistularum ab consulatu eius usque ad extremum tempus ad Atticum missarum; quae qui legat, non multum desideret historiam contextam eorum temporum.' Atticus' own letters were not published, though Cicero preserved them: _ad Att._ ix. 10, 4, 'Evolvi volumen epistularum, quod ego sub signo habeo servoque diligentissime.' 2. _Epistulae ad Quintum Fratrem_, in three Books, of the years B.C. 60-54. 3. _Epistulae ad Brutum_, originally in nine Books, of which only two remain. The present Book i. was really Book ix., and Book ii., which contains letters earlier than those in Book i., may have formed part of the original Book viii. 4. _Epistulae ad Familiares_, in sixteen Books, letters to and from friends, written B.C. 62-43. This title is not found in any MS. Late MSS. and old editions have 'Epistulae Familiares': for the title 'Ad Diversos' there is no authority. In the best MSS. the Books are titled separately by the name of the person to whom the first letter in each is written, _e.g._ 'M. Tulli Ciceronis epistularum ad P. Lentulum liber i.' For the colloquial style of the letters cf. _ad Fam._ ix. 21, 1 (to Paetus), 'Quid tibi ego in epistulis videor? nonne plebeio sermone agere tecum? nec enim semper eodem modo: quid enim simile habet epistula aut iudicio aut contioni? ... epistulas vero cottidianis verbis texere solemus.' The following works are now lost: (_a_) _Miscellaneous prose writings._--1. Panegyrics on Porcia (_ad Att._ xiii. 37, 3) and Cato, B.C. 45; and funeral orations written for other people to deliver (_ad Q.F._ iii. 8, 5, 'laudavit pater scripto meo'). 2. Memoirs of Cicero's consulship, written B.C. 60, in both Greek and Latin (_ad. Att._ i. 19, 10). He took great pains with this book, and was anxious that it should be well circulated (_ad Att._ ii. 1, 1). 3. A secret history, _Anekdota_, mentioned in letters of B.C. 59 and 44 (_ad Att._ ii. 6, 2; xiv. 17, 6). 4. _Admiranda_, a collection of wonders (Pliny, _N.H._ xxxi. 51). 5. _Chorographia_, a book on geography, mentioned by Priscian. The letters to Atticus show that Cicero was studying the subject in B.C. 59. 6. A work on law, _De iure civili in artem redigendo_ (Gell. i. 22, 7). 7. A translation of Xenophon's _Oeconomicus_, made when Cicero was about the age of twenty (_de Off._ ii. 87). (_b_) _Poems._--1. Cicero's earliest effort in verse was a poem in tetrameters, entitled _Pontius Glaucus_: Plut. _Cic._ 2, καὶ τι ποιημάτιον ἔτι παιδὸς αὐτοῦ διασῴζεται Πόντιος Γλαῦκος ἐν τετραμέτρῳ πεποιημένον.
