Nicolo Tommaseo was an important writer, lexicographer and politician, born in Sibenik, of Italian nationality (1801-1874). In 1830 he published “Nuova dizionario di sinonimi della lingua italiana”, and his voluminous “Dizionario della lingua italiana” in 1865-1879. He was also translating from Latin and Greek into Italian. In 1841-42 he published his “Canti popolari toscani, corsi, illirici, greci”. In accordance with his Dalmatian autonomistic views, he believed in the separate “Dalmatian nationality”, and was against the unification of Italy, and against unification of Dalmatia with banska Croatia (1861). He also violently criticized the French centralism. It is worth mentioning his close ties with many Croatian intellectuals, especially with Ljudevit Gaj and Ivan Kukuljevic-Sakcinski. With his beautiful elegiac and poetic work written in the Croatian language – “Iskrice” (Sparklets), and published in Zagreb in 1884, he entered the history of Croatian literature. Another important work is his elegy written in the Croatian ikavian language: “Suze sina zahvalnoga.” He also wrote pedagogic and philosophic treatises.
