The London Review of Books has a previously unpublished piece by Patrick Leigh Fermor, a celebration of the olive harvest that was written for the Greek edition of Mani (1958) but not used in it.
The unflagging swish! swish! swish! is the predominant sound all through the harvest. The olives that patter on the cloth like rain are piled in pyramids; children who are too young to be left alone in the empty village chase each other between the trees; dogs bark, mules nibble the new grass and white goats tear the leaves from the stripped twigs that cover the ground.
