Dímma

Dímma , son of Nath Í was a legendary scribe credited with writing a gospel-book, under miraculous circumstances, for St Crónán (qv) (fl. 7th century) of Roscrea. The little gospel-book now called the Book of Dimma (TCD, MS 59) was written towards the end of the eighth century for Dianchride. In the inscriptions signed by the original scribes, the names have been erased and Dímma's substituted. Enshrined in the twelfth century (probably during the short period when Roscrea was an episcopal see), by the fourteenth century it was in the hands of the local coarbal family of Ua Cuanáin. It reappeared in north Tipperary at the end of the eighteenth century.
