Seldom does a manuscript provide such insight to the apocalypse as the Reuchlin Codex. It was written in the 12th century, prior to the fall of Byzantium, it was adorned with very detailed marginalia. Around 1435, the manuscript was purchased for the Council of Basel. Since that time, Latin annotators, including Reuchlin, have added their comments. A team led by Erasmus used it as the basis for the Greek text of the Apocalypse in the modern era.
