Luís Vaz de Camões, sometimes rendered in English as Camoens or Camoëns, is considered Portugal's and the Portuguese language's greatest poet. His mastery of verse has been compared to that of Shakespeare, Milton, 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. His collection of poetry The Parnasum of Luís de Camões was lost during his life. The influence of his masterpiece Os Lusíadas is so profound that Portuguese is sometimes called the "language of Camões".
