We find ourselves in front of a huge olive tree. At ground level, its roots extend over a huge area. Its trunk is of spectacular diameter, and becomes more and more gnarled towards the start of the crown. Thick and gnarled branches support a huge crown. This olive tree, which seems to have been left to rest a number of years ago, would have previously been pruned to obtain the precious olives. How many sacks of olives will it have produced? How many cans of oil will it have filled? First the jars would have been ceramic, then glass and, in recent years, plastic. The age of this living organism is incalculable but it must be close to a thousand years old.
