Erasmus's original 1519 edition of the Greek New Testament was done in haste, and full of typographical errors. The errors in the first printing, and the high demand for a Greek version, led to a flurry of Greek editions in the early 1500's; the name "Textus Receptus" can refer to any of these, or any Greek edition printed from 1519 to about 1650. The name itself derives from the publisher's preface to a 1633 edition, containing the phrase "textum ergo habes, nunc ab omnibus receptum", meaning roughly "so you have the text now received by all".
