 Another theme that is included in Murillo's work is the opposition between man and nature; describing man with dyes of vitality, strength, unconsciousness and irrationality and the second as a rational entity, with limitations and conscience.After a year of Murillo's death, that is, in 1899, Cayetano Rodríguez Beltrán organized a National Tribute where the poet's artistic production was praised.In it some of the most important contemporary personages of the medium participated such as Justo Sierra, Amado Nervo, José María Vigil and Luis G. Urbina.
