In "Canto a Teresa" and in El diablo mundo (of which it constitutes an impo
rtant section), as well as in certain others of his poems, Espronceda expre
sses his "titanic" challenger of the powers and the more of heaven and eart
h. He develops a varied imagery of angels and devils to characterize his re
lationship with Teresa Mancha, as well as to explore facets of his own char
acter as a man and as a poet. So doing, he participates in a long tradition
of depicting women as both angels and devils, a tendency which gained part
icular currency in his century. In this regard, Espronceda attempts in his
poetry a Blakean "marriage of heaven and hell." Moreover, the poet refers t
o several verses on Lucifer and his fall in chapter 14 of Isaiah. He treats
the text of the scripture with profound irony as he utilizes it to elabora
te his portraits of Teresa and of himself with (and without) her. In these
allusions, Espronceda repeatedly reveals his unresolved ambivalence and "an
xiety of influence," in the realm of aesthetics, as well as of ethics.
