Scribes of the oldest part of the manuscript posted their names in two notes. In the fi rst note the final letter of the scribe’s name is seriously damaged. It is generally believed that his name was Mičьka (Мичька). The author proves that the scribe’s name is a derivative from the suffi x –ko (Mičьko). In the second note the name of the scribe is heavily damaged in the initial part, which results in a number of interpretations. According to the author’s studies the name of the scribe was Potamij (Потамий, gr. PÒtamoj).
