Text The text of the codex is a representative of the Byzantine text-type, with numerous pre-Byzantine readings. According to Scrivener "it exhibits strong Alexandrian forms." According to Streeter, in parts it has some Caesarean readings. Aland placed it in Category V, and it is certain that it is more Byzantine than anything else. The texts of Luke 22:43-44, and John 7:53–8:11 are omitted. In John 1:27 it has the addition (He shall baptise you with the Holy Spirit and fire). History It is understood that the manuscript originated in the imperial scriptorium of Constantinople and was dismembered by crusaders in the 12th century. In 1896 Nicholas II of Russia commissioned Fyodor Uspensky's Russian Archaeological Institute of Constantinople to buy the greater part of it for the Imperial Public Library in St. Petersburg. The codex was examined by Lambeck, Montfaucon, Hermann Treschow, Alter, Hartel, Wickholf, Bianchini,
