This article presents the basis of the movement initiated by the International Institute of Geopoetics. The transdisciplinary dimension of this research and creation field, founded by Kenneth White in 1989, and the predominance of some principles such as nomadism, outside and radical critics, join many concerns particular to travel writing, situated between literature and geography. The geopoetic approach opens the reflection as well on the poetic pole, which means the intrinsic link between the travel and the writing of the journey, as the reading pole, that needs to consider the reader’s subjectivity and his own connection to the world. The examination of Écrits sur le sable from Isabelle Eberhardt (who belongs to Swiss, French and Maghrebi literatures) allows us to explore many important notions in geopoetics as landscape, polysensoriality and movement.
