Ann Griffiths was a renowned hymn-writer and her compositions are major landmarks in the history of Welsh women’s writing. This volume is a compiliation of her early works. Griffiths was a committed member of the Methodist Society and her hymns were expressions of her personal spiritual experiences. Calvinistic Methodism encouraged members to develop a personal relationship with God and this experience was explored and discussed in the Methodist 'seiat' (fellowship). Her main inspirations included the intense language of the seiat and folk poetry. It must be noted that Griffiths was an oral composer and her hymns were not intended for congregational purposes. Griffiths’s maid, Ruth, memorised her compositions and eventually recited them to her husband, the preacher John Hughes, who noted them on paper. ‘Casgliad o Hymnau’ was edited by Thomas Charles from the Bala.
