Still, during this time, Grillparzer completed two of his greatest dramas, "Waves of the Sea and of Love" (, 1831) and "The Dream, a Life" (, 1834). "Waves of the Sea and of Love" dramatizes the story of Hero and Leander, as a poetic love-tragedy with an insight into character motivation that predates the psychological dramas of Ibsen. The work again is formed on classic models, but in this instance his feeling is so distinctly modern that it does not find adequate expression in Grillparzer's carefully measured verse. The subject has never been more happily treated than in some passages, which, however, are marked rather by lyrical than dramatic qualities. The poetic influence of Lope de Vega and Pedro Calderón de la Barca is also evident.
