an impressive ritual bath (mikve) dating to the time of the Second Temple (first century CE) was exposed inside an underground cave. An anteroom, flanked by benches, led to the bath. A winepress was excavated alongside the ritual bath.
The walls of the mikve were treated with ancient plaster and were adorned with numerous wall paintings and inscriptions, written in mud, soot and incising. The inscriptions are Aramaic and written in cursive Hebrew script, which was customary at the end of the Second Temple period. Among the symbols that are drawn are a boat, palm trees and various plant species, and possibly even a menorah.
According to Royee Greenwald and Alexander Wiegmann, excavation directors on behalf of the Israel Antiquities Authority, the inscriptions are a mystery. Some of the inscriptions might indicate names. The symbols depicted on the walls are common elements in the visual arts of the Second Temple period.
Simple: Jews lived in Jerusalem over 2000 years ago. That's the bottom line.
