Joannes Froben, a printer in Basel, Switzerland, persuaded the noted Biblical scholar Erasmus of Rotterdam to come to his city to prepare a Greek New Testament edition. Using manuscripts from the library at Basel University, the two men produced their Greek text in 1516. It became known as the textus receptus (Latin for received text). It was a basic guide for the translators of the King James Version. It began being replaced about two hundred years later by a critical text.1
