Death is a central theme in much of Kovačić's poetry, however this is not a reflection on his life outlook. His melancholy subjects came from outside events—such as his own and his brother’s affliction with tuberculosis—rather than from an internal disposition toward the morose. Jure Kaštelan, one of Kovačić's contemporaries, expressed that Kovačić was inclined both toward romanticism and realism in his poetry, and that Kovačić had an intense perception of life.[5]
