The Name That Shaped the Sonnet
The name's literary significance crystallized on April 6, 1327, when Italian poet Francesco Petrarch reportedly first saw Laura de Noves in a church in Avignon, France. He spent the rest of his life writing about her, producing 366 poems collected in the Canzoniere. That body of work refined and popularized the sonnet form, which became known as the Petrarchan sonnet and influenced centuries of European poetry.
