This thesis studies three of the most significant themes in the poetry of the Cuban Modernist, Julian del Casal. The poet's morbid fascination with death is characterized by an inability to adapt to his life environment, boredom, a strong self-destructive drive, and the concept of death as the ultimate joy and refuge. He reflects the Modernist aesthetic code in his cult of plastic and lyric beauty. An escapist, he sought refuge in an ideal world of perfection and elegance. This unobtainable goal resulted in deep melancholia and despair. The theme of love reflects a complete absence of passion and eroticism. The poet's categorical rejection of woman as a sensual object is accompanied by subtle insinuations concerning his own physical impotence and inability to love.
