The initial letters are written in gold ink and decorated. The letters are high, and round, and include breathings and accents. The letters are compressed only at the end of a line. Biblical scholar Samuel P. Tregelles found that the "letters are in general an imitation of those used before the introduction of compressed uncials; but they do not belong to the age when full and round writing was customary or natural, so that the stiffness and want of ease is manifest".
The manuscript has full marginallia, with the text divided according to the chapters (known as κεφάλαια / kephalaia), whose numbers are given in the margin, and their titles (known as τιτλοι / titloi) written at the top of the pages. There is another division according to the smaller Ammonian Sections, with reference to the Eusebian Canons (two early methods of dividing the Gospel text into sections). The number of sections in the Gospel of Mark is 233 (usually it is 235), the last section ending at 16:8.
The text of the manuscript was independetly collated by textual critic and manuscript hunter Constantin von Tischendorf in 1843, and by biblical scholar Samuel P. Tregelles in 1846. They compared their work at Leipzig for the purpose of mutual correction.: 150 Tischendorf cited the manuscript in his Editio Octava Critica Maior. Biblical scholar Caspar Gregory saw the manuscript in 1886. William Hatch published one page of the codex as photographic facsimile in 1939.
Birch dated the manuscript to the 10 or 11th century. Scholz dated it to the 10th century. Scrivener writes that it dates "scarcely before the tenth century, although the letters are in general an imitation of those used before the introduction of compressed uncials". The present palaeographers dated the manuscript to the 9th century. Tregelles: 203 and Gregory dated it to the 9th or 10th century. The manuscript is currently located in the Biblioteca Marciana (shelf number ms Gr. I, 8 (=1397)) in Venice.
