During the early days of archaeology some important finds went missing and their whereabouts remain unknown.
One important example was a seal uncovered during 1903-1905 excavations at Megiddo which subsequently disappeared. But a recent announcement may have brought its existence to light again.
Excavating Megiddo
Gottlieb Schumacher was an American-born German archaeologist excavating in what was then a region of the Ottoman Empire called Palestine. The Tel at Megiddo was one of the most intriguing sites for archaeologists. Situated on an important ancient highway it had evidence of multiple levels of occupation throughout Old Testament history.
