In the Greek Islands, one can seek out the home of Hippocrates, the father of modern medicine. In the area, one can also find an olive tree, supposedly dating from his time. If this is so, this tree would then be some 2400 years old. The trunk of this tree is very large but completely hollow. The tree is little more than thick bark. There are a few long, straggling branches, but they are supported by sturdy wooden poles every few feet. It has an occasional leaf here and there and might produce a few olives each year.
In the fields around, however, are olive groves in many directions. The strong, healthy, young trees with narrow trunks are covered with a thick canopy of leaves, under which masses of olives can be found each year. The tree of Hippocrates can still be called an olive by nature, in that it still shows the essential unique characteristics, but it has long since ceased to fulfill an olive's function. Tourists file up to inspect this ancient relic, having some link to a dim history, but the job of the olive tree passed long ago to many successions of replanted trees. Do you know any churches (or even people) like the tree of Hippocrates? The form is there, but the function is not. They have stopped reproducing and are satisfied just being big, or having a noble history. - Keith Copley
