Author and archaeologist Eilat Mazar has published an article in Biblical Archaeology Review suggesting that a small piece of clay with a seal imprint on it (called a bulla) might be the first-ever extra-biblical reference to the prophet Isaiah. In her article, she gives a historical overview of both King Hezekiah and the prophet Isaiah, followed by an overview of the locations in which both people were believed to have lived and worked—specifically temples in Jerusalem that have been under excavation for many years. Researchers found a bulla believed to have been created using one of King Hezekiah’s seals in one of these temples just three years ago. Another bulla has been the object of scrutiny ever since, and now, Mazar is suggesting the possibility that it came about from a seal belonging to the prophet Isaiah.
