The codex is an Alexandrian text-type manuscript written in uncial letters on parchment and dated paleographically to the mid-4th century. Scholarship considers the Codex Sinaiticus to be one of the most important Greek texts of the New Testament, along with the "Codex Vaticanus". Until Constantin von Tischendorf's discovery of the Sinaiticus text in 1844, the "Codex Vaticanus" was unrivaled.
