This outstanding, programmatic essay by @gbarnea.bsky.social has just appeared in Marginalia Review of Books.

I sense that we are on the verge of a paradigm shift which will see the approach outlined here becoming the norm in the study of Biblical literature and early Judaism.

I know it's a bit late for last weekโ€™s Torah reading.

But then again, Javier Milei's devar Torah at Davos was a hard act to follow.

Anyway, hereโ€™s an essay of mine on โ€œHow Archaeology Rewrote the History of Tefillinโ€, recently shared over @18forty.bsky.social's website.

This is a great opportunity to try crowdsourcing this problem.
Any ideas?

R. Reich, โ€œThe Asymmetrical Pottery Flask of the Early Roman (= Late Second Temple) Period in Judea,โ€ RB 132/4 (2025): 578โ€“604.

They appear in the Hasmonean period and disappear after 70 CE.

Reich tried, but ultimately was unable to suggest a plausible explanation for the strange shape, unique distribution, distinct chronology and ultimate function of these very odd vessels.

A recent article by Prof. Ronny Reich in the journal Revue Biblique examines the strange pottery flasks common in Early Roman (โ€œLate Second Temple periodโ€) Judea.

These are wonky vessels.
And they are found almost exclusively at Jewish sites in Judea proper (they rarely make it up north).

Asaf (my scribe) has gotten his micrography for the tefillin letters to almost the right size of about 1 mm in height.

To the right is a close-up of one of the tefillin slips from Wadi Murabbaสฟat; to the left, Asaf's writing with a reed on the flesh side of the papillary dermis of a goat.

Professor Ken Gemes reached out a few weeks ago to inform me that he was planning to give this online lecture, presenting my work in The Origins of Judaism.
This led to a wonderful exchange over email.

Prof. Gemes comes at this from his own fieldโ€”philosophy (he specializes in Nietzsche).

Adriano Virgili has just published on his blog (in Italian) an excellent review of my new book, Between Yahwism and Judaism.
He does a superb job distilling the main themes and arguments into a clear and thoughtful summary. Itโ€™s the first review to appear, and I was truly delighted to read it.

Prof. Aren Maeir just published an excellent response to recent pieces in Haaretz by Ofri Ilany and Elon Gilad on when โ€œJudaismโ€ first emerged.

I had considered penning a response myself, but Prof. Maeir beat me to it.
