Fortuny dome

The Fortuny dome was a theatrical device developed by Mariano Fortuny around 1902. It was a dome-shaped cyclorama, with its rear wall surfaced in plaster. When flooded with light, it created an illusion of infinite space, making it ideal for simulating sky and background effects. While effective, its dome shape occupied significant stage space and could distort projections. In a modified, curved, hanging form, it became a crucial element in modern stagecraft. This innovation was part of a broader evolution in stage lighting, moving towards more realistic and dynamic effects, largely influenced by figures like Adolphe Appia and Edward Gordon Craig, and enabled by advancements in electric lighting technology.12
