Other theories suggest that Old Croghan Man and other bog bodies were sacrifices to gods of fertility or harvest, and killed and buried to ensure good yields of cereals and milk. The arm-ring found with the body was made from waterlogged leather, strands of fibres and four bronze mounts. According to Louise Mumford of the National Museum, the leather ring was made with two strands of leather joined together through numerous small slits. The ring was initially removed from the body and wet cleaned to remove elements like peat from the leather. To prevent further decay of the waterlogged leather work and mould growth the arm-ring was stored in a 20% solution of glycerol and de-ionised water for two weeks in a process called consolidation. After drying and further chemical cleaning and treatment to prevent corrosion, the arm-ring was returned to the body for display. Croghan Hill is known as Bri Eile in Irish myth. In "The Boyhood Deeds of Fionn," we are told "At that time there was a very beautiful maiden in Bri Ele, that is to say, in the fairy-knoll of Bri Ele, and the name of that maiden was Ele. The men of Ireland were at feud about that maiden. One man after another went to woo her. Every year on Samain the wooing used to take place; for the fairy-mounds of Ireland were always open about Samain; for on Samain nothing could ever be hidden in the fairy-mounds. To each man that went to woo her this used to happen: one of his people was slain. This was done to mark the occasion, nor was it ever found out who did it."
