The Palestinian vocalization reflects the Hebrew of Palestine of at least the 7th century CE. A common view among scholars is that the Palestinian system preceded the Tiberian system, but later came under the latter's influence and became more similar to the Tiberian tradition of the
ben Asher school. All known examples of the Palestinian vocalization come from the
Cairo Geniza, discovered at the end of the 19th century, although scholars had already known of the existence of a "Palestinian pointing" from the
Mahzor Vitry. In particular, the Palestinian
piyyutimgenerally make up the most ancient of the texts found, the earliest of which date to the 8th or 9th centuries and predate most of the known Palestinian biblical fragments. [ibid]
