The history of the Masorah may be divided into three periods: (1) creative period, from its beginning to the introduction of vowel-signs; (2) reproductive period, from the introduction of vowel-signs to the printing of the Masorah[REF] (1525); (3) critical period, from 1525 to the present time.
The materials for the history of the first period are scattered remarks in Talmudic and Midrashic literature, in the post-Talmudical treatises Masseket Sefer Torah and Masseket Soferim, and in a Masoretic chain of tradition found in ben Asher's Diḳduḳe ha-Ṭe'amim, § 69 and elsewhere [REF].
