Mael-Isu of Derry

Mael-Isu (“Servant of Jesus”) of Derry is named in Eleanor Hull's The Poem-Book of the Gael as the author of the Irish hymn “Deus Meus”, and is dated there by his obit, 1038.

The English version of his hymn gathered here is by the Irish poet and physician George Sigerson, printed in Hull's anthology (London, 1913).
