Codex Cairensis

[3] According to its colophon, it was written complete with punctuation by Moses ben Asher in Tiberias "at the end of the year 827 after the destruction of the second temple"[4] (this corresponds to the year 895 CE, during the reign of Al-Mu'tadid).

More recently, further doubts on its authenticity have been cast by radiocarbon dating and other scientific techniques.

[2] It was stated, after scientific investigation, that the scribe must have been a different person from the vocaliser, and the manuscript must be dated to the 11th century, not the 9th.

[2] Umberto Cassuto relied heavily on this codex when producing his edition of the Masoretic Text, which means that in the Prophets his edition is closer to the ben Naphtali tradition than in the Torah or Writings.

Between 1979 and 1992 an editio princeps of the codex (text and masorahs) was published by a team of Spanish scholars.
