William Williams, Pantycelyn (also known as Williams Pantycelyn and Pantycelyn) (1717 – January 11, 1791) is generally acknowledged as Wales's most important hymn writer. He was also one of the key leaders of the 18th century Welsh Methodist revival, along with Daniel Rowland and Howell Harris. As a poet and prose writer he is today considered to be one of Wales's greatest writers.
He took deacon's orders in the Church of England in 1740 and was appointed curate to Theophilus Evans (1693–1767) in the parishes of Llanwrtyd, Llanfihangel Abergwesyn and Llanddewi Abergwesyn. Because of his Methodist activities he was refused ordination as a priest and from then on he committed himself entirely to that movement. He travelled throughout the country preaching and establishing seiadau, local fellowships of Methodist people, for the converts he won. He died in 1791.
In common with many other Welsh people whose names are less than unique, he was known by the nickname or bardic name of Pantycelyn, this being the name of the farm in the parish of Llanfair-ar-y-bryn where he lived for most of his life.
His virtuosity as a hymnwriter also earned him another nickname Y pêr ganiedydd (The sweet singer).
He wrote some of his work in English, but the great majority is in his native Welsh. He published his first work in 1744, the first part of Aleluia, a collection of hymns. This was followed by further collections:
He also published two collections of English hymns:
Possibly his best known hymn is Arglwydd, arwain trwy'r anialwch (in English, Lord, Lead Me Through The Wilderness, translated as the English Hymn Guide me, O Thou Great Jehovah), usually sung to John Hughes' Cwm Rhondda .
His hymns alone were not his only major contribution to the success of Calvinistic Methodism. He wrote two long poems on theological and religious themes. Golwg ar deyrnas Crist (A view of Christ's kingdom), 1756, deals with the whole history of salvation and God's grace in Christ. Bywyd a marwolaeth Theomemphus, 1764, deals with the religious experience of conversion and Christian living.
He also wrote a series of elegies in memory of various Methodist and other Christian leaders, including Griffith Jones (Llanddowror), Howel Davies (Pembrokeshire), George Whitefield, and Daniel Rowland.
Williams also wrote original prose works and translated others from English. They were mostly intended to be used by members of the Methodist fellowships he established.
In 1762 he published Llythyr Martha Philopur at y Parchedig Philo Evangelius eu hathro (Martha Philopur's letter to the Reverend Philo Evangelius her teacher) followed by Atteb Philo-Evangelius i Martha Philopur (Philo-Evangelius's reply to Martha Philopur) in 1763. These works were intended to defend and teach the significance of the 1762 revival at Llangeitho. The 1762 revival was a very powerful one and which manifested its power physically. As a result, Methodists in Wales were very often known as 'Jumpers'.
Works such as Doctor Nuptarum neu gyfarwyddwr priodas (Doctor Nupatrum or the marriage guide), 1777, and Drws y society profiad (An introduction to the experience meeting), 1777, were written as practical guides to Christian living for the converts who were members of the seiadau or societies.
