The seal — depicting the plant known variously as biblical persimmon, bosem or balsam, or even the Balm of Gilead — was discovered at the Foundation Stones of the Western Wall, according to a statement released Thursday.
According to the Israel Antiquities Authority, the biblical persimmon plant is unrelated to the modern-day fruit. It was used at the time of the Second Temple as an ingredient to produce the temple incense, perfume and other balms and medicines.
First-century Jewish historian Josephus Flavius wrote that Mark Antony gave Cleopatra received valuable persimmon groves that formerly belonged to King Herod. Scholars believe that this was so she could have an unlimited supply of the expensive balm extracted from the plant.
Some experts believe the plant was given to King Solomon by the Queen of Sheba, the IAA said.
Very good photo's from various perspectives and more description at this link.
I noticed that the head of the dove looks like the fruit.
