There is a memorial to William Morgan and Edmwnd Prys in St John's College Chapel, Cambridge, where they were students.
[5] Prys composed in the strict Welsh metres, and took an active part in the bardic life of his time.
[7] But Prys's reputation rests on his translation of the psalms into free Welsh verse, suitable for congregational singing.
A rendering of the psalms into the strict metres by Captain William Midleton had been issued in 1603,[8] and a freer translation of thirteen by Edward Kyffin had appeared in the same year.
In 1621, however, to a new issue of the Welsh version of the Book of Common Prayer was appended Prys's translation of the whole of the psalter.
