Greek and Hebrew in Byzantine Jewish Inscriptions

In Late Antiquity, the normal language for Jewish inscriptions in the diaspora was Greek. However, the Jews of Palestine, especially those in Galilee, also used Aramaic (Jewish-Palestinian Aramaic, or JPA) as their main language. Occasionally, one or two words in Hebrew were added, or Jewish religious imagery was included in the margins to point to the religious identity of the commissioner. On rare occasions, there is more substantial use of Hebrew alongside Greek. From at least the 10th century onwards, all known Jewish inscriptions are in Hebrew. This paper aims to investigate the background to this change and the reasons for it, and to attempt to date it more precisely. Particular attention will be paid to inscriptions in Greek and Hebrew. How can this be explained? Were the Hebrew and Greek elements carved at the same time, or was the Hebrew element added at a later period?
