The Mexican activist and painter Tina Modotti, the subject of one of Elena Poniatowska's most important novels, was born in Italy, migrated to the United States and then to Mexico. Naief Yehya and Fran Ilich, despite their non-Hispanic sounding names, are both Mexican writers and they both live in New York City. This chapter addresses authors like these who confound trajectories of national literary history, pointing toward a more general case by focusing on a few women writers whose gravitational orbits include "Mexican", but whose identities and writings cannot be limited to that national space. They include such established authors as Antonieta Rivas Mercado, Maria Luisa Puga, Carmen Boullosa, Elena Poniatowska, Margo Glantz, Margarita Oropeza, Cecilia Pego, and Cristina Rivera Garza. The chapter describes how intercultural and international mobility underlies Mexican literary historiography from its beginning, by reference to perhaps the most cited woman from the Mexican independence era, Frances Calderon de la Barca.
