[eng] To analyse the identity of a Greek community in Argentina, we cannot avoid using a metaphor of classical origin. Although in the beginning the migrant follows a life of journey like Ulysses, it ends up being more like a journey of life, like Alexander the Great. In the present article, based on an ethnographic work, we study the composition of the cosmology and the lived spaces of a Greek community in Argentina. The links and spaces they build up, far from being scattered, end up as a reaffirmation of a thalasocratic reference at the margin of time and space. This case results very appropriate in contemporary postmodern multicultural societies. These sea nomads have been able to recreate their representation and place in the world. For a Greek to live in Chios or in Ingeniero White is the same, because both are margins of the same sea that unites stories of life in the same journey of life.
