Published in 1562, Danese Cataneo’s epic-chivalric poem Amor di Marfisa had a wide but undervalued influence in Torquato Tasso’s masterpiece, Gerusalemme liberata . In this short essay I’ll provide the necessary evidences to demonstrate the existence of a deep connection between those two poems, and establish how it is organized. In particular, Cataneo’s literary legacy, which is underlined by a long list of quote, is strongly perceptible for what concerns the expression of feelings and thoughts. Amor di Marfisa , in this regard, gives to the young Tasso an unusual example of epic poem interested in characters’ psychology: aspects such as the self-analysis and the fragmentation of the ego are underrated in Ariosto’s Orlando furioso and all the other Italian poems in ottava rima , whereas they are fundamental in Cataneo’s poem. More than just an example, it represents for Tasso a training ground and a mine, where he founds themes and lexicon that later will be used in Gerusalemme liberata .
