Cino's works as
Latin jurist include a
Lectura in Codicem and an unfinished
Lectura in Digestum vetus. The
Lectura in Codicem (1312–1314), his most important legal work, was a commentary on the
Justinian Code which blended pure
Roman law with contemporary statutes and
customary and
canon law, thereby initiating Italian common law. In
Italian Cino is the most prolific writer of lyric poetry between
Guittone d'Arezzo and Petrarch, with a secure surviving corpus of twenty canzoni, eleven
ballate and 134
sonnets, notable for purity of language and harmony of rhythms. Most of these are love-poems celebrating Selvaggia dei Vergiolesi (d.1310). In the
De vulgari eloquentia (2.2)
Dante assigns him prime place amongst love poets in Italian. His friendship with Dante appears to have been a long-standing one, although it may be that Terino da Castelfiorentino, not Cino (as has been thought), was the author of one of the replies to Dante’s early ‘A ciascun alma presa e gentil core’ (
Vita Nova 3). Cino composed a
canzone on the death of
Beatrice in 1290, and there are another six sonnets to Dante from Cino and five by Dante to Cino, with Dante initiating the exchange in two cases. They seem to have been particularly close during the first years of Dante’s exile. In the
De vulgari eloquentia Dante links the two of them in his poetic rolls of honour as ‘Cynus et amicus eius’. He also addresses the third of his letters (1306?) ‘to the Pistoian exile’. On the death of Dante in 1321 Cino wrote the celebratory ‘Su per la costa, Amor, de l’alto monte’. There are, however, two sonnets (one of which is not definitely by Cino) which are critical of the
Divine Comedy. Cino is the link between the
Dolce Stil Novo and the greater lyric poetry of Petrarch, whose musicality his own practice anticipates. His poetic correspondents include
Guido Cavalcanti and Onesto da Bologna, who jibed at the dreaminess of the Dolce Stil Novo. Cino was also close to his fellow student
Giovanni d'Andrea. The opening of the canzone, ‘La dolce vista e’l bel guardo soave’, is cited respectfully by Petrarch (
Canz. 70) and the whole poem is re-written in ottava rima in
Boccaccio’s
Filocolo (5.62–5). Petrarch also wrote a sonnet on his death (
Canz. 92). == Portrayals ==
