Digital Library of Georgia: 16th-century liturgical codex now freely available in the Digital Library of Georgia. “The book, or codex, is a leather and metal-bound liturgical volume of hand-lettered manuscript pages written in Latin and estimated to have been created around 1580. It contains text from the Catholic Tridentine Mass, adopted at the Council of Trent a decade earlier, and includes excerpts from the book of Matthew and musical notation for hymns.”
