An example which is probably of a similar age can be found in the Life of St. Tatheus (English Translation) in which a stolen cow leaves a hoofprint miraculously imprinted in stone. While this life was written in the 12th C., it deals with a 'Dark Age' period and is probably built on earlier materials. It centres, along with the life of St. Gwynllyw (English Translation) and a number of other British saints' lives, on the coastal plain of the Severn, where many of our wonders lie.
