Cicero (106-43 BCE)Tusculanae Disputationes , in Latin, illuminated manuscript on paper [Tuscany, probably Florence, second half 15th century].A fine, complete, dated humanist copy - signed by the scribe Pietro Landino - of the great Roman statesman, lawyer and scholar’s foray into Greek philosophy, composed shortly after the death of his daughter Tullia. 233 x 168mm. 110 leaves, complete, collation: 1-1110 , catchwords survive, 28 lines in a humanist script, ruled space: 150 x 90mm, initials in blue, rubrics and marginal name references in red, one illuminated white-vine initial extending into border (some foxing and spotting, a few scattered wormholes, some dampstaining to gutters, some gutters reinforced). 18th-century vellum over pasteboards (a little browned, spine peeling). Provenance : (1) Written by Pietro de Landini of Volterra: colophon on f.110 ‘M. T. Ciceronis Tusculanarum questionum liber quintus ex et ultimus explicit scriptus per me Petrum de Landinis Vulterranum Anno d[o]m[in]i 14?4’ (Colophons , no 15,656). The third digit of the date has been changed to a ‘1’, but the watermark (a flower) is close to Briquet 6659 (Pistoia, c.1484). Early catalogues linked Petrus de Landinis to Cristoforo Landino (1424-1498), the celebrated commentator of Dante, humanist and tutor of Lorenzo de' Medici and his brother Giuliano, who studied at Volterra under Angiolo da Todi. (2) Paulus de Bargalglis: ownership inscription on f.110: ‘Hic liber est Pauli de Bargalglis’. There is a mention of a Paolo Bargagli in Siena in 1444 (see Siena e il suo territorio nel Rinascimento , II, 1987, p.38). (3) 17th-century inscriptions on f.1v, including one that suggests that the altered date in the colophon is not recent: ‘Continet Codex iste Ciceronis Questiones Tuscukanas, scriptus fuit a Petro Landino anno 1414 - ut in fine habetur’. (4) Aloisio (Luigi) Baroni (1726-1809), Servite monk: his ownership inscription ‘Volumen 22 Bibliothecae F Aloysii de Baronis 1749’ on f.2.

Regarded as the most intensely felt and expressed of all Cicero’s philosophical works, written by Cicero between 45 and 44 BCE while mourning the death of his daughter in his Tusculan villa, the Tusculan Disputations take the form of dialogues between friends, examining through a Stoic lens the various states of happiness, including consideration of death, grief and suffering, and their possible amelioration through philosophy and virtue.
