Luís Vaz de Camões, (c. 1524 – June 10, 1580) 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 (in Portuguese and in Spanish) and drama but is best remembered for his epic work Os Lusíadas (The Lusiads)
you should check, I know you like writing and stuff haha. I guess its not exactly the stuff you're into, although its always good to increase your library if you really want to be a writer. I'm not sure if it'll have the same impact on you than it has on most of admirers of literature who are Portuguese-speakers.
Here's a little secret: I don't read. But, he has been added to my ever growing reading list, which I lovingly call my "WTF you doin' lazy asshole, read stuff now!" list, so thanks.
