Codex Sinaiticus is one of the most celebrated and important books in the world. Handwritten well over 1,600 years ago, it contains the Christian Bible in Greek, including the oldest surviving complete copy of the New Testament. Originally discovered at St. Catherine's Monastery at the foot of Mount Sinai, its surviving leaves are now preserved across four libraries worldwide, with the largest portion held at the British Library.

Codex Alexandrinus is one of the four great uncial codices of the Greek Bible. It contains the vast majority of the Septuagint and New Testament, and was the first of the great uncials to become accessible to modern scholars.
