It is one of the most important representatives of the Textus Receptus, the first generation of printed editions of the Greek New Testament in history.
It was named Editio Regia because of the beautiful and elegant Greek font it uses, known as the Grecs du roi.
The oldest manuscript used in this edition was the Codex Bezae, which had been collated for him, "by friends in Italy" (secundo exemplar vetustissimum in Italia ab amicis collatum).
Estienne made only a few changes in the Erasmian Novum Testamentum: for example, he added verse Luke 17:36, which he took from Codex Bezae.
[3][4] Manuscripts γ', δ', ε', ϛ', ζ', η', ι', ιε' were taken from the King Henry II's Library (Royal Library of France, now Bibliothèque nationale de France).
