A virtual event presentation by Dr. Jon Greenberg.

About The Event:

This program will explore the symbolic and halachic significance of the olive tree. The questions we’ll examine include:

• Neglected agricultural and political reasons that the olive oil Chanukah displaced an earlier symbol of Chanukah,
• Why the 15th of Av became a day for matchmaking,
• How the social and technological history of olive use mediates a five-hundred-year-old debate about how to read the Talmud, and
• The beautiful lesson about family relationships that the Psalms draw from the biology of the olive tree.
