Jacopo Sannazaro (28 July 1458 – 6 August 1530) was an Italian poet, humanist and epigrammist from Naples.
He wrote easily in Latin, in Italian and in Neapolitan, but is best remembered for his humanist classic Arcadia, a masterwork that illustrated the possibilities of poetical prose in Italian, and instituted the theme of Arcadia, representing an idyllic land, in European literature. Sannazaro's elegant style was the inspiration for much courtly literature of the 16th century, including Sir Philip Sidney's Arcadia.
