[1] He was a forerunner of Marinism, anticipating the tastes and values of the Baroque years before Seicentismo became the leading fashion in Italian literature.

[2] One of the founding members of the Accademia degli Incogniti,[3] Casoni was a close friend of Giovanni Francesco Loredan and Tommaso Garzoni.

[5] After declining an invitation to reside at the court of the Duke of Savoia, Casoni was named dogal ambassador to Serravalle, and elected Knight of the Order of Saint Mark by Doge Antonio Priuli on 7 March 1619, in recognition of his consistent contribution to the Republic through his literary publications.

[2] This last honour probably occasioned the two editions of Opere del signor caualier Guido Casoni (1623 and 1626), as well as his new richly illustrated edition of Tasso's Jerusalem Delivered, for which Casoni composed a new biography of the author, Vita di Torquato Tasso (1625).

[2] Finally in 1632, in addition to the Incogniti Ode, Casoni published his last poetic work, a twenty-two canto illustrated poem on the ideal state (praised by Angelo Grillo as «vera filosofia di stato»), Gli emblemi politici.
