Argentine literature began around 1550 with the work of Matías Rojas de Oquendo and Pedro González de Prado (from Santiago del Estero, the first important urban settlement in Argentina), who wrote prose and poetry. They were partly inspired by oral aboriginal poetry—in particular, according to Carlos Abregú Virreyra, by the "lules", "juríes", "diaguitas" and "tonocotés". A symbiosis emerged between the aboriginal and Spanish traditions, creating a distinct literature, geographically limited (well into the 18th century) to the Argentine north and central regions, with the province of Córdoba as its center, due to the foundation of the National University of Córdoba. Two names stand out from this period: Gaspar Juárez Baviano, and Antonia de la Paz y Figueroa, also known as "Beata Antula".
