Composed for Bridges's text by George J. Elvey (PHH 48), DIADEMATA was first published in the 1868 Appendix to Hymns Ancient and Modern. Since that publication, the tune has retained its association with this text. The name DIADEMATA is derived from the Greek word for "crowns."
The tune is lively and buoyant (though the harmony lacks life, especially the inner voices). Sing a strong unison on stanza 3 if using the Hal H. Hopson (PHH 219) descant. A number of good choral and brass arrangements, useful for festive occasions, are available.
