Photographer’s Note

In ancient history, tanning was considered a noxious or "odiferous trade" and relegated to the outskirts of town, amongst the poor. Indeed, tanning by ancient methods is so foul smelling that tanneries are still isolated from those towns today where the old methods are used.
In northern Cameroon these methods are still actuals.
People use leather for waterskins, bags, harnesses, boats, armor, quivers, scabbards, boots and sandals. Skins typically arrived at the tannery dried stiff and dirty with soil and gore. First, the tanners would soak the skins in water to clean and soften them. Then they would pound and scour the skin to remove any remaining flesh and fat. Next, the tanner needed to remove the hair fibers from the skin. This was done by either soaking the skin in urine, painting it with an alkaline lime mixture, or simply letting the skin putrefy for several months then dipping it in a salt solution. After the hair fibers were loosened, the tanners scraped them off with a knife.
Once the hair was removed, the tanners would bate the material by pounding dung into the skin or soaking the skin in a solution of animal brains.
The traditional tanner might use his bare feet to knead the skins in the dung water, and the kneading could last two or three hours. Depending on the type of dung used, the mixture might be rather acidic, causing irritation or minor burns during its prolonged contact with human skin.
It was this combination of animal feces mixed with decaying flesh that made ancient tanneries so odiferous.
Leftover leather would be turned into glue. Tanners would place scraps of hides in a vat of water and let them deteriorate for months. The mixture would then be placed over a fire to boil off the water to produce hide glue.
