Thanks for this welcome new journal!
It may be a minor point, but the Gabriel Inscription--of uncertain provenance--may not be "the only known text from the Dead Sea region written on stone." De Vaux excavated in Qumran a text inked on limestone. Though it is smaller and fragmentary, it may be worth noting. KhQ 2207 was uncovered in locus 129 on 26 Feb, 1955. Pages 360-362 in Lemaire, A. 2003 Inscriptions du Khirbeh, des grottes et de ʻAïn Feshkha. Pp. 341-88 in
Khirbet Qumrân et de Khirbet Qumrân et ʻAïn Feshkha. II. etudes d’anthropologie, de physique et de chimie, eds. J.-B. Humbert and J. Gunneweg. Fribourg: Academic Press.
Thanks to Stephen for this note, a welcome supplement to my initial characterization of the Gabriel Inscription. I will check up Lemaire's edition of this text. Further, some Qumran jars (including the cylindrical jar in The Schøyen Collection) have Hebrew letters inked on them. During a recent visit to the Rockefeller Museum, I studied jar KhQ1401, where I see three Hebrew letters (yod, alep, inverted nun), where Lemaire (pp. 354–5) reads the Latin LXI. The nun might be inverted because it 'bumps' into the jar handle.
