What does writing Greek books mean at the height of the Cinquecento in Venice? The present volume provides fascinating insights into Greek-language book production at a time when printed books were already at a rather advanced stage of development with regards to requests, purchases and exchanges of books; copying and borrowing practices; relations among intellectuals and with institutions, and much more. Based on the investigation into selected institutional and private libraries – in particular the book collection of Gabriel Severos, guide of the Greek Confraternity in Venice – the authors present new pertinent evidence from Renaissance books and documents, discuss methodological questions, and propose innovative research perspectives for a sociocultural approach to book histories.
