JUDAISM
The Babylonian Talmud
The Mishnah together with the Gemara of the Babylonian academies: law, argument and narrative.
The Babylonian Talmud runs to 37 tractates, 4,325 passages. The whole of it is held here and free to read, searchable by reference or by the words in it.
The edition held here is Rodkinson, in English, in the public domain, from Wikisource.
It sits on the estate's shelf of 106 sacred works, beside the complete Douay-Rheims Bible, an atlas of the places named in scripture, a timeline and a genealogy.
