The manuscript belonged to the monastery of the Dominican Order. It was borrowed by Desiderius Erasmus and used by him in his edition of the Novum Testamentum (1516). Sometimes he used some of its marginal readings instead of main text readings (e.g. Acts 8:37; 15:34; 24:6-8). In result some of its readings became a part of the Textus Receptus.
It was examined by Battier (for John Mill), Wettstein.
