The Textus Receptus, or "Received Text" (as it was later called), was the Greek manuscript used for the latin Vulgate and the earliest English translations of the Bible.
Robert Estienne (aka Stephanus) (1503-1559) edited and printed four editions of the Greek New Testament books from 1546 to 1551. The third edition of 1550 and the fourth edition of 1551 are the same text, but the fourth edition is noteworthy for its division of the New Testament books into chapters and verses, a system still in use today.
