The aim of the International Colloquium between PhD students and post-doctoral researchers (RACTA) is to provide a comprehensive overview of studies on Late Antique and Christian Archaeology, Art History, History, and Early Christian Literature being carried out by young scholars from all over the world. RACTA also provides a forum to share ideas and engage with researchers and specialists from different disciplines who can add value to individual research. The variety of topics addressed by the 23 speakers of this second edition demonstrates an interdisciplinary methodological approach, confirming the infinite possible relationships between the different disciplines and reinforcing the multidisciplinary orientation given to the Colloquium since its first edition.
