From a story in The Jewish Press:
Quote: "The City of David excavations of the Jerusalem Hebrew University on Mount Ophel, at the foot of the southern wall of the Temple Mount compound, have yielded a sensational discovery: a seal (bulla) with the name of King Hezekiah (727-698 BCE)."
"King Hezekiah’s bulla was discovered in a garbage heap that was dumped during or shortly after Hezekiah’s time, from a royal building that was used to store food. This building is part of a series of buildings, including a gate and towers, which were built in the second half of the tenth century BCE (the time of King Solomon), as part of the Ophel fortifications of the new government complex that connected the city of David with the Temple Mount."
"The Hezekiah seal bears the inscription: “Hezekiah (son) Ahaz King of Judea,” with an emblem of the sun emblem with tilted down wings and two icons of the Ankh (symbol of life)."
