About 1658 he is found starting on the great work of his life — the publication of Welsh books for the use of the peasantry . He issued the first part of the work of Rhys Prichard (of Llandovery ) in 1659 and the second part (although no copy is extant) appeared shortly afterwards. An end to the work of publishing came with the Restoration and Hughes was obliged to leave Meidrym . We know little about him in the time of persecution but it is said that he continued to preach in Carmarthenshire and that he kept schools .
He m. Catherine , daughter of John Daniel , the second mayor of Swansea and it was there that he made his home from then on.
About 1670 he succeeded in resuming the work of publishing Welsh books and the third part of the work of Vicar Prichard appeared that year. He received the support of Churchmen and Nonconformists and published four parts of the work of the vicar , in one volume, in 1672 , with in addition, Llyfr y Psalmau, ynghyd â Thestament Newydd ein Harglwydd , and Catechism Mr. Perkins . He was in London during this period and met Thomas Gouge and Charles Edwards ; he co-operated with these two for over ten years. He was again in London in 1677 and published two composite volumes — Tryssor i'r Cymru and Cyfarwydd-deb i'r Anghyfarwydd . Then, in 1677-8 , he was able to make a reality of one of his dreams — to issue a cheap edition of the Bible in Welsh . He produced another edition of the work of Vicar Prichard in 1681 and, on this occasion, gave it the title of Canwyll y Cymru , by which Prichard 's verses have ever since been known. In 1683 he arranged for the publication of a booklet which was similar to the work of the vicar , viz. Cynghorion Tad i'w Fab by Henry Evans . With three other men he translated John Bunyan 's famous work and this was published in 1688 under the title of Taith neu Siwrnai y Pererin . It is evident that he did very much to help forward the plans of Thomas Gouge in regard to Wales whilst continuing to preach to the scattered congregations of Carmarthenshire and its surrounding district.
He died at Swansea in 1688 , his will being proved on 16 July . Stephen Hughes is important not only as an apostle of Nonconformity but as one of the men who began to convert the masses in Wales into conservers of the Welsh language.
