This volume presents the proceedings of the II Jornadas Predoctorales en Estudios de la Antigüedad y de la Edad Media, held at the Autonomous University of Barcelona, on the 19, 20 and 21st November 2014. The book follows the princAal subdivision of the conference sessions: Ancient East; Greece, from Archaic to Hellenistic Times; Republican, Imperial and Late Antique Rome; Early Medieval Literature; Late Middle Ages and Humanism. The papers focus on the use of the texts in different sciences of Antiquity and Middle Ages (History, Archaeology, Philology, etc.) and how that use is a common tool to study the past, considering the literary source as the main nexus among discAlines. Quoting Thucydides, a text is a ????? ?? ???? (an eternal possession), so, even though the papers in this volume deal with different chronologies and subjects, the approach of the study is always based on texts.
