Writing Bilingually is an amazing research project led by Sara Migletti on early modern self-translation.
It aims to create a catalogue of prose self-translations produced in Italy and France between 1465 and 1700. The database is work in progress.
You can access the catalogue here: https://sites.google.com/view/writing-bilingually-1465-1700
