The volume represents a choral homage from colleagues from several universities, students and friends to Silvia Lusuardi Siena, on the occasion of her 75th birthday, as a sign of esteem and gratitude for her long career as a teacher and scholar. The 49 contributions address themes of archeology, methodology, material culture, numismatics, architecture, history, history of art, touching on territorial areas in which Silvia Lusuardi has conducted intense and multi-year excavation campaigns and research projects (Luni and Liguria, Milan and Lombardy, Cividale del Friuli and Veneto). The title of the publication "Under the profile of the method" takes up an expression that often resonates in his dialogues with students and collaborators, acting as a sema of his approach to archeology, which has made it a solid reference for many, especially his own from the point of view of the method. Silvia Lusuardi is part of that first effective generation of medieval Italian archeology, perhaps with wider spaces but still entirely to be plowed, from which those who came after cannot ignore. Silvia Lusuardi Siena (Milan, 17 May 1946) was Full Professor of Medieval Archeology at the University of Udine (1990-1994) and at the Catholic University of Milan (1994-2016). In the latter university, he also held the teaching of Archaeological Research Methodology and held the role of Director of the Institute of Archeology (1998-2010) and of the School of Specialization in Archaeological Heritage (2014-2016). He is currently a member of the Board of Directors of the Ambrosiana Academy of Milan (Class of Ambrosian Studies) and President of the Lunensi Study Center. In 2003 he 're-founded' together with Maria Pia Rossignani the series “Contributi di Archeologia”, intended for the presentation of the results of the research carried out in the archaeological field at the Catholic University. He participates in the Scientific Committee of the journal “Temporis Signa. Archeology of Late Antiquity and the Middle Ages ”, published by the Italian Center for Studies on the Early Middle Ages Foundation in Spoleto.
