The Derrynaflan Hoard
Derrynaflan, County Tipperary
In 1980 a father and son using a metal detector on the island of Derrynaflan, in a bog, found a hoard including a magnificent silver chalice, a paten and a strainer. The finders and the landowners fought the state in the courts over who owned it, and the case changed Irish treasure law.

The Ledger of Lost Artifacts and Civilizations
Not every mystery needs a lost continent. This book investigates fifty-nine real and often overlooked puzzles from the ancient and modern world: a temple older than farming itself, astonishing structures, out-of-place artifacts, and technologies lost to time. Each case is weighed honestly, with a clear ledger of the case for and against, so you can make up your own mind. Some cases collapse under scrutiny. Others remain genuinely unexplained. All of them are stranger than Atlantis.
