This study, whose theme is romantic love, dictated by personal motivation and for being a timeless theme in all cultures and literatures, aims to demonstrate the marks of identity and otherness of capeverdean and Brazilian literatures, in Oswaldo Osório and Vinícius de Moraes, as parts of a whole, that of the history of literature, through the analysis of the love lyric problem at the various levels of construction of the text, the mapping the similarities and singularities in Vinícius de Moraes and Oswaldo Osório based on the theory of comparative literature, and signaling the contributions of the Brazilian and Cape-verdean literary systems in the construction of literature.The approach of these two poets, compels us to a comparatism respecting the limits imposed by the different time and culture of the two authors and, by extension, the romantic poetry, lato sensu, as a whole. The theoretical basis of this study is that of the comparative literature. In this sense, the research is based on a theoretical perspective that is linked to the orientation of Comparative Literature, in a dialogue close to the studies of Julia Kristeva (2005), Harold Bloom (1991), Tania Carvalhal (2003), Eduardo Coutinho (1994), Earl Miner (1996, Machado and Pageaux (2001), Sandra Nitrini (2000), among others. When examining the issue of comparativism and intertextuality, we take into account the existence of "un macrosistema marcado como un campo común de contactos entre los sistemas literarios nacionales" (Abdala Jr., 1989, p. 16). Bibliographic and field research serves as a basis to justify the social and literary context in which the works emerge, the symptoms and analysis of the observed elements.This methodology allowed us to work on the dialogism proposed by Mikhail Bakhtin (1998 and, listening to the "voices" of the selected poems and exploring the two aspects of dialogism, which are the concepts of intertextuality, within the discourse, and the verbal interaction between the enunciator and the enunciator of the text.As for the structure, this presents: an introduction presenting the investigative categories such as the hypotheses of the work, the objectives, and the justification of the theme, as well as the theoreticalmethodological framework. In chapter I, entitled Historical-Social Journey on Love, we point out the xiii historical roots from (1) Ancient Greece, through the great philosophers such as Plato, who conceived love as being a journey to perfection, Aristotle who presented friendship as the greatest virtue of life, Lucretius who regarded love as a mental disorder, and Ovid who judged love as a kind of war and not a mission for cowards; the thinkers related to (2) Christianity -among the various names, we highlight the Apostles, St. Augustine and Jesus Christ; the latter revealed in the Holy Scriptures as being the source of Love which is the supreme virtue. Also in this chapter, we present the main characteristics of (3) courteous love, based on André Chaplain's Courteous Love Treatise, and (4) romantic love, the...
