''Os Lusíadas'' ((:uʒ luˈzi.ɐðɐʃ)), usually translated as ''The Lusiads'', is a Portuguese epic poem by Luís Vaz de Camões (sometimes anglicized as ''Camoens'').
Written in Homeric fashion, the poem focuses mainly on a fantastical interpretation of the Portuguese voyages of discovery during the 15th and 16th centuries. ''Os Lusíadas'' is often regarded as Portugal's national epic, much in the way as Virgil's ''Aeneid'' was for the Ancient Romans, or Homer's ''Iliad'' and ''Odyssey'' for the Ancient Greeks. It was first printed in 1572, three years after the author returned from the Indies.〔
The poem consists of ten cantos, with a variable number of stanzas (1102 in total), written in the decasyllabic ''ottava rima'', which has the rhyme scheme ABABABCC, in a total of 8816 lines of verse.
The poem is made up of four sections:
*An introduction (''proposition'' – presentation of the theme and heroes of the poem)
*''Invocation'' – a prayer to the ''Tágides'', the nymphs of the Tagus;
*A ''dedication'' – (to Sebastian of Portugal), followed by narration (the epic itself)
*Narration (the epic itself) - starting in stanza 19 of the canto I, in media res, starting in the midst of the action, with the background story being told later in the epic.
The narration concludes with an epilogue, starting in stanza 145 of canto X. The most important part of ''Os Lusíadas'', the ''arrival in India'', was placed at the point in the poem that divides the work according to the golden section at the beginning of Canto VII.
