Codex Sinaiticus ca. AD 350

British Museum, London

The “God is love” graphic, above, is copied from the Codex Sinaiticus.  Codex Sinaiticus is a manuscript of the Christian Bible written in the middle of the fourth century and contains the earliest complete copy of the Christian New Testament. The name ‘Codex Sinaiticus’ literally means ‘the Sinai Book’. The hand-written text is in Greek. The New Testament appears in the original vernacular language (koine) and the Old Testament in the version known as the Septuagint (LXX, ca. 130 B.C.), that was adopted by early Greek-speaking Christians. Codex Sinaiticus is one of only four great codices that have survived to the present day.  They are written in a certain uncial (broad single-stroke letters using simple round forms) style of calligraphy using only majuscule (capital) letters, written in scriptio continua (meaning without regular gaps or spaces between words). Words do not necessarily end on the same line on which they start. All four of these manuscripts were made at great expense in material and labor, written on parchment or velum (animal skins) by professional scribes.

‘Codex’ means ‘book’. By the time Codex Sinaiticus was written, works of literature were increasingly written on sheets that were folded and bound together in the form that we still use today. This book format was steadily replacing the roll format which was more widespread just a century before. These rolls were made of animal skin (like most of the Dead Sea Scrolls) or the papyrus plant (commonly used for Greek and Latin literature). Using the papyrus codex was a distinctive feature of early Christian culture. The pages of Codex Sinaiticus, however, are made of animal skin parchment. This marks it out as standing at an important transition in book history. Before it we see many examples of Greek and Latin texts on papyrus roll or papyrus codex, but almost no traces of parchment codices. After it, the parchment codex becomes the norm.

In Christian scribal practice, nomina sacra is the abbreviation of frequently used divine names or titles, especially in Greek manuscripts of the Bible. A nomen sacrum consists of two or more letters from the original word spanned by an overline; in the case of the Sinaiticus graphic, above, the theta and sigma are the first and last letters in the Greek word Theos, or God.
