⁂ "Davies's Welsh grammar in Latin, Antiquae linguae Britannicae ... rudimenta appeared in 1621. In 1632 he published a Welsh-Latin dictionary, Antiquae linguae Britannicae ... dictionarium duplex. Davies wrote the Welsh-Latin section of the dictionary himself, and used Thomas Wiliems's work for the Latin-Welsh sections, abridged and revised. His dictionary was subsequently used and cited as an authority in the English dictionaries of Thomas Blount (1656) and Edward Philips (1658), and Dr Johnson had a copy of the Dictionarium duplex in his library." - Oxford DNB.
