Isaiah bulla
The Isaiah bulla, or the Yešaʿyah[û] Bulla, is a Hebrew-inscribed bulla (clay seal impression) discovered in the Ophel area of ancient Jerusalem and dated to the Iron Age IIB, or more specifically, the late 8th or early 7th century BCE. The inscription, written in the Paleo-Hebrew alphabet, includes the word "le-Yešaʿyah[û]" ("Belonging to Isaiah"), and then, the letters "nby," which was reconstructed by the original excavator as "prophet", though the reading remains debated. The bulla was recovered in 2009 during excavations directed by Eilat Mazar at the City of David.
