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".

Os Lusíadas, usually translated as The Lusiads, is a Portuguese epic poem written by Luís Vaz de Camões and first published in 1572. It is widely regarded as the most important work of Portuguese-language literature and is frequently compared to Virgil's Aeneid. The work celebrates the discovery of a sea route to India by the Portuguese explorer Vasco da Gama (1469–1524). The ten cantos of the poem are in ottava rima and total 1,102 stanzas.
