Earth Inferno is the first book by the English artist and magician Austin Osman Spare, written when he was 18.

Conceived as an anti-establishment reaction to the publicity surrounding his inclusion in the Royal Academy summer show in 1904, the book was developed over the remainder of that year and was eventually published in 1905.

[1] Influenced heavily by Dante's Inferno, the book is decorated with poems and aphorisms in an aesthetic style.

It clearly shows the design influence of Spare's early supporter Charles Ricketts.

Published when the artist was 18 years of age, the book introduces the reader for the first time to Spare's fundamental concepts such as Kia, Ikkah and Sikah and Zos.
