Why ancient butter keeps turning up in Irish bogs
In bogs across Ireland, people keep stumbling into their forebears鈥 valuables.
While at at work in Emlagh bog near his home in County Meath, Ireland, peat farmer Jack Conway discovered a buried some 16 feet down, reports Smithsonian聽Magazine. 聽It turned out that he had come across a 2,000-year-old piece of 鈥渂og butter.鈥
The stuff is exactly what it sounds like: blocks of cow鈥檚-milk butter buried in a bog thousands of years ago, and typically stored in a container of wood or skin.聽Researchers propose that聽the blocks were buried there because it 鈥 聽with their coolness and lack of oxygen,聽peat bogs can be nearly as handy as modern appliances.聽 These conditions allowed the butter to remain more or less preserved, and hidden, over long periods.聽
Bog butter might have had mystical purposes as well.聽A 2010 survey of literature聽 cites several authors who refer to it as a customary object in thanksgiving rituals, or as a means of inducing the gods鈥 favor.聽
Savina Donohoe, curator of the Cavan County Museum, emphasized the high value of butter at the time in an interview with Fox News, saying it would have been 鈥.鈥 And she referred to its possible religious significance. 鈥淚t may have been an offering to the gods,鈥 she said.
People find pieces every few years or so.聽 In 2009, a 77-pound, 3,000-year-old oak barrel full of butter was discovered, as Smithsonian notes. Four years later, a 鈥渢urf cutter鈥 鈥 used by peat farmers who cut and sell it as a source of fuel 鈥 ran into a 100-pound, 5,000-year-old chunk.聽
From 1817 to 1997, 274 findings were reported in total.聽 claimed that the practice of depositing chunks of butter in bogs lasted as late as the end of the 18th聽century, although radiocarbon dating places the practice farther back, between 400 BC and the 13th聽century AD.
After several thousand years, the chunks in its texture more than the butter consumed now,聽said Andy Halpin, assistant keeper in the Irish National Museum鈥檚 antiquities division, in an interview with the Irish Times.
鈥淭heoretically the stuff is still edible 鈥 but we wouldn鈥檛 say it鈥檚 advisable,鈥 said Mr. Halpin.
