In 1821, peat cutters discovered a body similar to a mummy, pinned down by two wooden stakes deep in the mud. The body’s face still held red hair and a beard, their teeth were well preserved, and a hoop of willow was wrapped around their throat. But this wasn’t the dry, hot climate of Egypt but a cold and rain-sodden bog of Ireland. Later assessment suggested that these were the remain ...[Read More]

The indigenous group prospered for thousands of years until its fall in the 13th century (potentially due to severe drought). However, thousands of years before this collapse, severely soggy conditions lasting for many centuries likely inhibited the civilisat ...[Read More]
