Which composer wrote the 1918 opera Das Wunder der Heliane, whose English title is The Miracle of Heliane?

Erich Wolfgang Korngold wrote the 1918 opera Das Wunder der Heliane, whose English title is The Miracle of Heliane.

Korngold was an Austrian composer who became known for both concert music and influential Hollywood film scores. Das Wunder der Heliane is an early stage work from his European career, written before he moved permanently into American film composition. The opera’s German title is often translated as The Miracle of Heliane.

Korngold’s operatic output is sometimes overshadowed by his music for films such as The Adventures of Robin Hood, for which he won an Academy Award. His operas reveal the late-Romantic harmonic language and dramatic intensity that also shaped his cinematic scores.

The title can be confused with other works connected to miracle stories or with Korngold’s opera Das Wunder der Heliane itself. The question concerns the composer, not the librettist or the opera’s later translator. Korngold’s full name is Erich Wolfgang Korngold.
