"Bath’s [Bath, England - see below] Roman curse tablets have been added to the UNESCO Memory of the World register of outstanding documentary heritage." Source: June 2014 press release, The Roman Baths - Bath.
"The 130 Roman curse tablets can be seen at The Roman Baths [see below], which is managed by Bath & North East Somerset Council.
"They are the personal and private prayers of 130 individuals inscribed on small sheets of lead or pewter, and cast into the hot spring at Bath, and date from the 2nd-4th century AD. The earliest known surviving prayers to a deity in Britain, they are messages in Latin to the Roman goddess Sulis Minerva, from people who had suffered an injustice, asking for wrongs to be put right and for revenge."
