In the Emlagh peat bog residing in County Meath, Ireland, Jack Conway was removing moss blocks when he stumbled upon a 22-pound chunk of butter. According to the Irish Times, the discovery, which is at least 2,000 years old, is not rare in Ireland, where residents regularly come across pieces of the dairy when digging up peat moss for their homes&rsquo heating systems. Bog butter is typically discovered inside a wooden object, such as a bucket, keg, barrel, dish, or butter churn. You can even spot the 2,300-year-old chunk of bog butter in the archaeology section of the National Museum of Ireland. Its most famous peat-preserved exhibits &ndash the bog bodies, intact ancient human remains, also recovered from peat bogs, are housed in the same wing. One popular argument holds that food items were buried in bogs because they provide the optimal environment to prevent spoiling. Other beliefs include that individuals may have planted the butter as a sacrifice to the gods or as a way to keep valuables safe from robbers and invaders.
