Afonso Henrique da Costa Guimarães, known as Alphonsus de Guimaraens, was a Brazilian poet. The poetry of Alphonsus de Guimaraes is substantially mystical and involved with Catholicism. His sonets display a classical structure, and are profoundly religious. They become increasingly sensitive as he explores the meaning of death, of the impossible love, of solitude and of his inadequacy regarding the world. However, the mystical tone marks in his works a feeling of acceptance and of resignation towards life, suffering and pain. Another characteristic aspect of his work ids the use of spirituality in relation to the feminine figure, which is considered to be an angel, or a celestial being. As a result of that, Guimaraes shows himself not one as a Symbolist but also a follower of Neo-romanticism.
