Cormac's Glossary, written in the 9th Century, is often considered to be the first non-Classical language dictionary. Ó Cléririgh (of 'Four Masters' fame) printed one in the 1640s and Richard Plunkett compiled a Latin-Irish dictionary in 1662. This was only in manuscript form, and was later used by Edward Lhuyd, the Welsh linguist. The first widely published English-Irish dictionary was printed in 1732 in Paris, and compiled by Ó Baeglaoich and Mac Cruitín.
