In an ancient bog at the foot of a fairy-haunted hill, peat-cutting work lays bare the body of a giant. Carbon dating suggests that the man died at the height of the Iron Age, around 275 B.C.; forensic examination shows that he died hard, stabbed through a lung and then decapitated with an axe. After killing him, his executioners chopped his body in half at the diaphragm, and at some point, perhaps while he was still alive, they also inflicted two pairs of unusual wounds on him. Deep cuts almost severed both his nipples, and his arms were vigorously pierced so that twisted lengths of hazel withy could be threaded through from side to side, presumably to pinion him. After that, his mutilated torso was sunk in a pool where, over the years, bog moss grew up to cradle and cover him, until he became part of the mire itself.
As the dead man’s assailants were most likely perfectly aware, the unusual properties of the bog and the moss combined to preserve his remains. The sour waters of high bogs are as acidic as vinegar, and they support practically no life, yet they contain bog oak – which deeply tans organic matter – and sphagnum moss, which uniquely binds both nitrogen and oxygen, inhibiting bacteria. Trapped in this nutrient poor, anaerobic environment, human remains are preserved almost intact; bones may be leeched and gradually demineralise, but flesh and wood, horn, fur, hair and textiles can and do survive for millennia. So when ditching work uncovered the torn remains that archaeologists now call “Old Croghan Man” outside the little village of Croghan, in County Offaly in the heart of Ireland, investigators could still make out the pores on his skin and inspect the well-manicured fingernails that showed that he had done no manual work and hinted at high status. They could calculate that he had once stood 6 feet 5 inches [1.95m] tall: a great height now, freakish for his day. And they could feel reasonably certain that that height had been made possible by an unexpectedly rich diet, predominantly comprised of meat. Continue reading
