2nd, while Wiki covers surface of PRE, McDowell is gold mine on contents, sources & editing.
Big picture of PRE is that, beyond 1st century CE, dialogue between Christians & Jews, & after 630 or whenever Muslims as well, was much heavier than one might believe from today. It died off in Western Europe in the Empire after pogroms of First Crusade, in France after Jewish well-poisoning canards really erupted in the crackdown on Albigensians, & in Spain in the post-El Cid era, as the Reconquista got its second wind. In Middle East heartland, I think it was more gradual withering.
Notes:
1st, idea that the serpent of Genesis is Satan enters Judaism via PRE, which likely takes it from Islam & Samael, as did Christianity, tho hints of it go back as far as OT pseudepigrapha. The “Occultation of Abraham,” author notes, clearly came from Muslim world & is first attested in Judaism here.
2nd, apparently some knowledge of "Qumran" scrolls — NOT the actual scrolls at Qumran, but the represented documents — existed circa 800 CE.
3rd, “chair for Elijah” at circumcisions appears to originate here.
4th, McDowell asks how much Jews of this era knew of the “pseudepigrapha,” & within that, how much came fr Christians, or Muslims, & how much was directly maintained.
5th, Geza Vermes invented term “rewritten bible” & later defended it against claims it was not a unitary class of literature. Sefer ha-Yashar led him to idea. The literary category extends as late as the Historia scholastica.
6th, PRE author may have known Testaments of the Twelve Patriarchs, or at least traditions from it.
7th, re author noting pseudo-Jonathan likely depended on PRE rather than traditional idea that reverses that. Wiki cites McDowell putting PJ’s provenance in 12th c Italy. (Historia scholastica was 12th c France.) Wiki page also has counterarguments with conclusion pJ was composite text.
8th, covered in more depth below, I am unconvinced by McDowell’s claims of direct or even semi-direct dependence of PRE on Cave of Treasures, a Christian rough parallel to Book of Jubilees. This is main reason it doesn’t get a fifth star. Nonetheless, his critique is a fascinating look at the time and place behind PRE, at a point where Judaism and Christianity in the Middle East, perhaps pushed by the rise of Islam, were undergoing a final separation, despite many Christians’ belief that happened centuries earlier.
And, THIRD time this year, my massive notes exceed Goodreads' limit! So, trimming for
