In the years 2014-2019, I had an honour and pleasure of working in the team led by Professor Robert Wiśniewski at the University of Warsaw that researched the roles, careers and the place in the Church of the presbyters in the late antique West (between 300 and 700 AD). One of our main objectives was the production of the freely accessible database collecting evidence with English translation and commentary on presbyters and allowing the variety of thematic queries.
The project was completed in 2019 but we not only maintain the website but we still add some new material to the database and revise the entries.
