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.

This 5th-century manuscript is an important survival of the Greek translation of Jeremiah. The surviving parchment pieces show evidence of wear and glue marks, suggesting that after their original use, they were repurposed as binding material in other books before being rediscovered and preserved.

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.
