Literature is an essential unit of a culture and social, political and historical changes in a society impact both culture, language, and particularly, literature. Although there are various languages in the world, literature is the main communication that connects people from different cultures and countries. Literature: Lingua Franca of Cultures, thus, is designed to depict the similarities between different cultures within similar issues and topics. To meet this purpose, the book contains thirteen chapters, each of which was designed to clarify, exemplify and interpret a specific theme, underscored by remarkable authors from different cultures. Within this scope, each chapter respectively presents a topic: diseases, male gaze, children, intimate relations, antagonists or protagonists, human nature, war and depression, parenthood, death and suicide, God and religion, geography and human, revenge, and alienation. In each chapter, notable literary texts from different authors were analyzed to foreground the thematic and contextual similarities. This book, hence, provides readers different perspectives and interpretations to better internalize the common themes and messages of world classics. Although there are various studies of the remarkable senior academicians in the comparative literary field, hopefully, Literature: Lingua Franca of Cultures would contribute to this field both for the academicians and readers.
