 For some time the notations were useless, as no one in the world had any knowledge of how to read Stepanov's method.It was not until Stepanov's original primer was found in the archives of the Mariinsky Theatre that the notations were able to be deciphered.Not all of the notations are complete, with some being rather vague in sections, leading some historians who have studied the collection to theorize that they were probably made to function simply as "reminders" for the Ballet Master or "régisseur" already familiar with these works.
