Ann Griffiths (born April 1776, Llanfihangel-yng-Ngwynfa, Montgomeryshire, Wales—died August 1805, Llanfihangel-yng-Ngwynfa) was a Welsh hymnist whose works are characterized by complex scriptural allusions, bold figures of speech, and deep spiritual fervour. They are written in a somewhat uneven metre that is troublesome to performers.
Ann Griffiths recited her hymns to her maid, Ruth Evans, who kept them alive in her memory. Griffiths died in 1805 after giving birth to her only child. Shortly thereafter the maid and her husband committed the hymns to writing, and they were first published in the same year as their composer’s death. The standard edition is that of Sir Owen Edwards, Gwaith Ann Griffiths (“The Works of Ann Griffiths”), 1905.
