This year has seen a flood of publications from Brepols related to Gnosticism, mysticism, and apocrypha in antiquity. Two more I have just caught wind of are the following:

Pierluigi Piovanelli, Apocryphités. Études sur les textes et les traditions scripturaires du judaïsme et du christianisme anciens, collects studies from one of the most important and prolific scholars of ancient Christian apocrypha and pseudepigrapha. For more and TOC, see the book’s page at Brepols here.

Simone Claude Mimouni and Madeleine Scopello (eds.), La mystique théorétique et théurgique dans l’Antiquité gréco-romaine, Judaïsmes et christianismes, offers a volume of wide-ranging papers on mysticism in Second-Temple Judaism, earliest Christianity, and Gnosticism.
