A 4th-century Septuagint papyrus containing the Song of Solomon. The single surviving folium was physically torn vertically in half from top to bottom. The surviving piece is the right half of the original leaf. Reading left-to-right, the recto preserves the ends of lines, while the exact same parchment piece flipped over to verso preserves the beginnings of lines.

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.
