The poetry of Sophia de Mello Breyner Andresen: the poet and the political participation defends the thesis that the poet has the mission of revealing the beauty of the poetry interrelated to life. The poet develops several tasks to accomplish his mission such as the criticism of the perverted life on his concept of divided time and the announcement of a poetic and political project of making the most of that beauty. On this mission, the poem is like a man, who is born and faces difficulties the same way it does; the poem is also a poet that commits to the same cause, deepening the social retort and keeping the alliance between poetry and life. Therefore, the poet, as well as the poem, is an example of a fair way to relate to himself and the others, revealing that poetry is didactic. This research is not based on theories, but on the poetic and political ideas compiled on Sophia Andresen s essays about poetry and art; on these essays the poetry, the poet, the poem and life have recurrent significations and constant implication. This thesis concludes that Sophia Andresen is the example of a poet that accomplishes the mission explained above because of the tasks mentioned before and also the poetic invention which says the poem is a man, connecting, therefore poetry and life on her work.
