This paper is the result of the analysis of six fictional writings from the 17th and 18th centuries from the library of Samuel von Brukenthal (1721-1803), the governor of the Principality of Transylvania between 1777 and 1787. The research was conducted in order to search and extract aspects concerning the political imaginary of the time. These writings are fantasy and science-fiction novels and they comprise Description de l´Isle des Hermaphrodites by Thomas Artus, Andrew Michael Ramsay’s Voyages de Cyrus, L´Espion Turc à Francfort, Ludvig Holberg’s Voyage de Nicolas Klimius dans le Monde Souterraine, Lettres d´une peruvienne by Françoise de Graffigny and L’An 2440 by Louis-Sébastien Mercier. The first literary duet, Isle des Hermaphrodites and Voyages de Cyrus, illustrates, among other things, the concept of anti-utopia, the need for social and political change that was increasingly appearing in the writings of the time, the ideas of kingship and enlightened despotism. The second literary pair, L´Espion Turc and Voyage de Nicolas Klimius, brings forward another political desideratum of fantasy writers of the time, namely the establishment of an internal and international equitable jurisprudence, but also the birth of a new, non-Eurocentric, perspective on the world. The third duet, Lettres d’une peruvienne and L’An 2440, emphasized what in the Modern Age would be radical political ideas, such as women’s emancipation, but also exemplifies the idea of a perfect society, envisioned by the Enlightenment-Age author Louis-Sébastien Mercier far in the future, in 2440. The analysis of these novels reveals both some similarities between the writings, but also specificities and emphases on different political, social and cultural issues that the authors saw as problematic in real life.
