Preuilly sits at the heart of a prehistoric factory. The soil here is chalky, with many limestone outcrops. With this type of geology comes veins of
silex (flint) - a material vital to prehistoric man. In some areas of the world, man's pattern of settlement is dictated by the availability of water. In the south Touraine water is abundant everywhere, so it was undoubtedly because of the flint that man came to live in the Claise and nearby valleys in the Early Paleolithic period, and the evidence of flint tool making has been found in many places in the district. Occasionally specialist tools made of shell or other material are found, but most tools from this time are flint.
Flint is very heavy - much heavier than the limestone, therefore it is worked where it is found. Very often, archaeologists notice that there are two piles of waste, that have fallen each side of the flint knapper's leg. These piles of waste can tell you how high the individual was sitting and what type of tools they were making. Archaeologists are able to reconstruct the flint nucleus by studying the pattern of detritus at some sites. This type of examination of the evidence gives a good understanding of the technical aspects of flint tool manufacture.
Recently I attended a flint knapping demonstration at our local museum. The flint knapper was a local teacher and archaeology enthusiast, Bertrand. He taught himself the technique, based largely on observation of ancient tools and 'factory' sites, which can reveal much about how the flint was worked in prehistoric times.
He uses the tools available to prehistoric man: 3 sizes of red deer antler, a boxwood club or hammer, hard river stones (hammer stones), smaller abrasive sandstones, some deer antler tips and a deer hide to protect his left thigh and knee.

Step one for the modern exponent of the art of flint knapping is to remove your mobile phone from your pocket. It seems being walloped with a hammer stone never does them much good.
Next, inspect your lump of flint closely. It may be a
dalle (thin and flattish) or a
rognon (nodule). The
dalles will strike like a bell if they are sound and without flaws. It is more difficult to judge the quality of a nodule, but you hope for a nucleus that will strike a variety of tools from alternating sides. Each lump of flint is coated with a cortex of limestone, which sometimes needs to be removed before you can assess the best way to strike. The flint is dark grey, brown or orangey, somewhat translucent looking. The limestone cortex is pale and a few millimetres thick.

of lames (blades) to the right.
The first tool he made was a scraper, done by striking the fat end of the nodule and causing a piece the size and shape of a scallop shell to shear off. It was quickly neatened along the edge with some deft taps from the antler. This type of tool, and evidence of its manufacture, has been found in great numbers in the Brignon valley not far from Preuilly. Simple tools like this can be retouched several times in their useful lifetime.
Turning the nodule over, he then created a knife with a fine, very fragile edge. This was followed by using the face created to strike off a series of long thin flakes using the antler hammer. These types of tools were all typical of the Early to Middle Paleolithic, Bertrand said, or up to 40 thousand years ago.
Clockwise on the hessian mat: flint dalle, flint nodule,
polishing stones, antler nibblers and hammers, boxwood club / hammer
and a couple of pieces of tuffeau (soft limestone) to sit on.
When producing the
lames or
lamelles as they are called in French, it is important to prepare the striking platform each time between hammer blows, to ensure that the stone will shatter along a regular and predictable line. Here in the Claise Valley they apparently made a special style of
lame in the late Paleolithic (40-30 thousand years ago)
known as
livres de beurre, a technique specific to this area. Striking off
lames allows a multitude of sequential tools, from scrapers to burins. The little flakes could be glued into a bone handle and used to cut sinew and blood vessels when butchering game.
In the latest phase of flint tool making, the techniques evolved to produce bifacial points, often of considerable size (30+ cm and 1cm thick). In French these are known as
feuilles de laurier. They are essentially a big knife, which could take a whole day to make. The
feuilles de laurier differ from the earlier blades because they are symmetrical. This means they can be retouched when they lose their keeness. Earlier sliver like blades have a different angle on each side and cannot be retouched. Small 'laurel leaves' can be glued to a lance to form a spear tip using resin or wax and twine. Such spears are designed to wound an animal, which would then have been tracked until it collapsed from loss of blood and exhaustion.
So much flint was used in prehistoric times it is now difficult to find big pieces suitable for making the larger tools. The toolmaker's level of skill is also nothing like the prehistoric artisans - even as a modern experimental archaeologist, you simply don't get enough practice at working the material. The quality of modern flint working tools is poorer. Modern deer are much smaller than the giant creatures that lived in prehistoric times.
It is clear that the southern Touraine and adjoining northern Vienne, from Bossay to the confluence of the Claise and Creuse rivers, was a significant tool making location. Not everywhere had a local source of flint and tools from this area were traded and circulated widely throughout France, especially to areas like Brittany, which has much harder rock and no flint.

PS Bertrand and I share a family name. He and I have a theory that we have a common ancestor from Germany, so are distantly related. Members of the family probably reached England and France due to the widespread practice of hiring German mercenaries from the Middle Ages onwards.
Suddenly, we are harvesting nectarines - small, but not too bad. Our big old tree has a worthwhile crop ready now. I am amazed it didn't drop all its fruit like the other nectarine trees did in the dry.
The Doyenne de Comice pears look fantastic, of good size, but not yet releasing when I move them, so they are not ripe enough to pick. The nashis are small, like little golden apples. I don't know if they will swell up with the rain, but I hope so.
Several of the apples have some ripe fruit already, and it is much better quality that the previous two years. There is relatively little disease or insect infestation. Time to make apple jelly!
The peaches are coming on, still hard, but no unsightly black spots this year, so I assume there has been no hail.
