The Aramaic alphabet is ancestral to what alphabet known variously by scholars as the Jewish script?
Hebrew alphabet The Hebrew alphabet (Hebrew: אָלֶף־בֵּית עִבְרִי‎ , "Alefbet Ivri "), known variously by scholars as the Jewish script, square script and block script, is an abjad script used in the writing of the Hebrew language, also adapted as an alphabet script in the writing of other Jewish languages, most notably in Yiddish (lit. "Jewish" for Judeo-German), Djudío (lit. "Jewish" for Judeo-Spanish), and Judeo-Arabic. Historically, there have been two separate abjad scripts to write Hebrew. The original, old Hebrew script, is known as the paleo-Hebrew alphabet (which has been largely preserved, in an altered form, in the Samaritan alphabet), while the present "Jewish script" or "square script" to write Hebrew is a stylized form of the Aramaic alphabet and was known by Jewish sages as the Ashuri alphabet (lit. "Assyrian"), since its origins were alleged to be from Assyria. Various "styles" (in current terms, "fonts") of representation of the Jewish script letters described in this article also exist, as well as a cursive form which has also varied over time and place, and today is referred to as cursive Hebrew. In the remainder of this article, the term "Hebrew alphabet" refers to the Jewish square script unless otherwise indicated.
Mosaic authorship Mosaic authorship is the Jewish and Christian tradition that Moses was the author of the Torah, the first five books of the Hebrew Bible/Old Testament. The books do not name any author, as authorship was not considered important by the society that produced them, and it was only after Jews came into intense contact with author-centric Hellenistic culture in the late Second Temple period that the rabbis began to find authors for their scriptures. The tradition probably began with the law-code of Deuteronomy, and was then gradually extended until Moses, as the central character, came to be regarded not just as the mediator of law but as author of both laws and narrative.
