Luís Vaz de Camões is considered Portugal's and the Portuguese language's greatest poet. His mastery of verse has been compared to that of Shakespeare, Vondel, Homer, Virgil and Dante. He wrote a considerable amount of lyrical poetry and drama but is best remembered for his epic work Os Lusíadas (The Lusiads). His collection of poetry The Parnasum of Luís de Camões was lost in his lifetime. The influence of his masterpiece Os Lusíadas is so profound that Portuguese is sometimes called the "language of Camões".
