Perhaps the worst problem with the narrative of the ‘Decadència’ is that it discourages people from studying the period to which it refers. The "decadence" of Catalan literature in the early modern period, therefore, depends on one's presuppositions and point of view. The "decadent" aspect of this period is in part a construction of the writers and critics of the Renaixença that aims at establishing a clear difference between the movements. Important authors writing in Catalan during the early modern period include Francesc Fontanella, Francesc Vicenç Garcia, and Josep Romaguera. Both Fontanella and Vicenç Garcia wrote theatrical and poetic works, including sonnet sequences, religious verse, and even erotica. Romaguera was renowned for his oratory skills, conserved in sermons published in Castilian, as well as the only book of emblems ever published in Catalan, the Atheneo de Grandesa (1681). The earlier work Tirant lo Blanc by Joanot Martorell (1490) was considered the best chivalric romance by Cervantes in his Don Quixote, which was quite an influence for writers of the period. Other works of the early modern period include popular poetry such as goigs and broadsides.
