This work analyzes the narrative poem "O Elixir do Paje" by Bernardo Guimaraes. In addition to Escrava Isaura (1875), the Minas Gerais writer played a relevant role as a poet, ignored by critics. Thus, he begins with a brief exposition of his poetic production, highlighting his performance as an introducer of Pantagruelian poetry, produced between the 1840s and 1860s by the poets and students of the Largo Sao Francisco Law School. It is exposed as theoretical bases for analysis, starting from the poem's view as part of the long tradition of the narrative poem, to an exposition of questions related to the grotesque type, specifically as conceptions of Victor Hugo (1802-1885) and Mikhail Bakhtin (1895-1975), to finally analyze the processes of structural elaboration of the poem.
