The codex was held at Saint Catherine's Monastery on Mount Sinai in Egypt and was found by Constantin von Tischendorf in 1853, who took away only the uncial text (Luke-John) — along with Codex Tischendorfianus IV — and brought it to the Bodleian Library in Oxford, where it is now located.
Kodek itu disimpan di Biara Santa Katarina di Gunung Sinai, Mesir dan ditemukan oleh Constantin von Tischendorf pada tahun 1853, yang hanya membawa pergi teks uncial (Lukas-Yohanes) — bersama dengan Codex Tischendorfianus IV — dan membawanya ke Perpustakaan Bodleian di Oxford, di mana naskah itu sekarang disimpan.
