If you asked people whom their favorite Biblical prophet is, there’s a strong chance they would answer Isaiah. Sure, Moses gets all the accolades, received the tablets, and is the most important; but Isaiah is the prophetic book most quoted by authors of the New Testament. For Christians, Isaiah predicts the coming of the Messiah, the death of Jesus and the Virgin Birth. So, it is particularly auspicious that in a stunning article published today in Biblical Archaeology Review archaeologists announced that they have stumbled upon the first physical evidence for the existence of the prophet Isaiah.

The evidence itself comes in the form of a small piece of clay (an impression left by a seal), a mere 0.4 inches long, which appears to bear the inscription “Isaiah the prophet.” It was unearthed as part of excavations of a previously undisturbed pile of debris at the Ophel excavation in Jerusalem. The dig is headed by Eliat Mazar who provides a description of the discovery, significance, and translation of the seal in an article published in this month’s issue of BAR. The debris contained figurines, pottery fragments, pieces of ivory and some clay seal impressions, known as bullae. These impressions were created when the owners of the seals stamped their seals into the soft clay and include the mark of King Hezekiah, previously reported here at The Daily Beast.

According to Mazar, “alongside the bullae of Hezekiah… [were] 22 additional bullae…among these is the bulla of “Yesha‘yah[u] Nvy[?]” which is most straightforwardly translated as “Isaiah the Prophet.” Given the importance of Isaiah to religious history, this seal impression is of great significance to Jews and Christians alike.
