I am in the middle of a permaculture design course which meets every Friday. Permaculture is a way of designing that copies from, and strives to be in harmony with, nature. So that includes farming and gardening methods, building design, and lifestyle. I've learned a lot about permaculture along the way, especially from my good friend Jan Bang who is a real expert. But the course is helping fill in the gaps, reorganize my thinking, and giving me lots of new ideas to try. The teacher and fellow students are great people. It takes place at the Chava V'Adam Ecological Education Center in Modiin. A highly recommended place to visit and experience. Check it out.
Why am I telling you all this here? First, because the Garden of Gethsemane has about a dozen seriously old olive trees. The million dollar question is: "how old? Did Jesus really rest under these same trees?" I know, that's two questions. From what I've learned, there aren't any 2000 year old olive trees still alive. Or even 1,980 year old ones in this case. But still they are quite a beautiful site.
Secondly, the name Gethsemane in Hebrew is "Gat Shmanim", or oil press. Apparently there was an olive press, possibly in Mary's grotto next door. Notice the big round stones for crushing olives in the background in the painting that hangs on the wall there (just below Jesus' right hand):
